Silly season is upon us once again. Soccer's January transfer window is open, which means rumors are flying about which players will be headed for greener pastures over the next month. While the transfer window is always full of surprises and we never know exactly what will happen, we do have a good idea of which players might be on the verge of a transfer. Here are 10 players who might be on the move this January.

Philippe Coutinho

Potential destinations: Barcelona

There was already speculation that Coutinho wasn't long for Liverpool and is destined for a move to Barcelona. Then, just as the window opened, a since-deleted Nike advertisement that touted Coutinho's arrival at Camp Nou sent the rumor mill into overdrive. At this point, there isn't a chance that the Brazilian doesn't depart Liverpool for Barcelona at some point, whether it be this month or next summer. Liverpool might be wary about losing one of its star players just before the club begins its run in the Champions League knockout round, but Barcelona is one of the few clubs in the world that could splash enough cash to make the Reds change their minds.

Alexis Sanchez

Potential destinations: Manchester City, Manchester United, Chelsea, Bayern Munich

With only months remaining on Sanchez's Arsenal contract, Arsene Wenger and the Arsenal backroom find themselves in quite the pickle. They can either A) keep Sanchez for the spring and risk him leaving on a free transfer to a league rival when his contract expires, or B) sell their star player, recoup what they can and maybe find a destination for him outside of England, where the Gunners wouldn't have to face him multiple times a year. Neither is an enviable option. Sanchez is Arsenal's best player and a fan favorite. There would be a lot of heartache around North London if he trades Arsenal red for Manchester City blue.

Leon Goretzka

Potential destinations: Bayern Munich, Liverpool

Goretzka is one of the best young talents in German soccer and coveted by almost every top club in Europe. He can leave on a free transfer this summer, so expect Schalke to do everything in its power to cash in on its top prospect. There have been hints that a move to Liverpool to link up with fellow German and former Borussia Dortmund manager Jürgen Klopp might be in the offing, which would be a coup for the Reds. But then Bayern Munich confirmed its interest in him, which might put this transfer saga on ice. Just as every top club covets the young German, almost every young German covets a shot to play for Bayern. If that is indeed an option, it would be surprising to see him sign anywhere else.

Riyad Mahrez

Potential destinations: Arsenal, Chelsea, Tottenham

Mahrez went from obscurity to stardom in 2015-16, as he led Leicester City on its incredible run to the Premier League title. Many expected him to leave Leicester the following summer, but the Algerian attacker stuck around, with a far less spectacular season in 2016-17. So far this season, he's regained a bit of the form from two seasons ago, only now the Foxes aren't fighting for anything expect a mid-table finish. His ambitions have outgrown the club, and a move to a member of the EPL elite could be in the offing. Arsenal and Chelsea stand as the favorites for his services.

Danny Rose

Potential destinations: Manchester United

Rose has made no bones about wanting a pay bump that Tottenham seems unlikely to give. Luckily for him, Manchester United is in the market for a left back. United fullback Luke Shaw and manager Jose Mourinho have butted heads this season, leading to a lot of speculation that Mourinho would like to find a replacement. Outside of Juventus' Alex Sandro -- who is most likely to move to Chelsea if he moves from Turin -- Rose is the best option. However, an injury suffered in a recent match against Swansea may toss a wrench in his transfer ambitions. It's doubtful any top club would shell out for Rose in January if it turns out he'll have to be shelved for a few months.

Kepa Arrizabalaga

Potential destinations: Real Madrid

It's been a poor season for Real Madrid so far, and a lot of fingers have been pointed at keeper Keylor Navas as a contributing factor to the current mess. Many fans, including those among the club's executives, might feel it's time to move on from Navas and finally sign a true heir to Iker Casillas' throne. Athletic Bilbao's Kepa is could be that heir, and he could be signed soon. The 23-year-old is already one of the top keepers in La Liga, and he could become a fixture at the Santiago Bernabeu for years to come if his signing is completed. That is, if Real doesn't sign him, then turn around and ink David De Gea or Thibaut Courtois this summer.

Thomas Lemar

Potential destinations: Arsenal, Liverpool, Chelsea

Lemar was heavily linked to a move to Arsenal over the summer, but selling the 22-year-old winger was a step to far for Monaco in its summer fire sale. Now, though, it seems the club may have reversed course and is willing to let the Frenchman go for a hefty fee. Arsenal is still in the running for the skilled winger, but Liverpool has reportedly stepped up its interest as it braces for Coutinho's potential move away from Anfield. Chelsea is also rumored to be in the mix for Lemar.

Arturo Vidal

Potential destinations: Chelsea

The departure of Nemanja Matic to Manchester United over the summer has made Chelsea much less effective than it was a year ago, when it won the league. Chelsea manager Antonio Conte needs bruising center backs who can distribute long and short as well as bang in a goal when needed for his system to flourish. There isn't a player in the world who fits that criteria more than Vidal, who excelled in Conte's system while the two were at Juventus together between 2011 and '14. If Vidal does make the jump to London, the Blues just got a lot more dangerous.

Jonny Evans

Potential destinations: Manchester City

Central defenders are at a premium in the Premier League, and there isn't a club at the top of the table that wouldn't love landing Evans, one of the league's best defenders over the past two seasons. Evans was a top prospect at Manchester United years ago and spent nine years with the club, but he never lived up to his potential at Old Trafford. The move to West Brom in 2015 has helped him finally meet his potential. At this point, though, he's outgrown the Baggies and is ready to rejoining the league's elite. And wouldn't you know it, United's Noisy Neighbors need a central defender and have plenty of cash to spare. If Evans does end up at City, as expected, the move is sure to ruffle some feathers on the red side of Manchester.

Ross Barkley

Potential destinations: Chelsea, Tottenham

Barkley hasn't played a minute for Everton this season, and it might stay that way. A hamstring injury on the eve of the Premier League season has kept him out of action since August, so he's been relegated to watching the Toffees from the stands. It's been a bad season for Everton, so it would come as no surprise if he hasn't liked what he's seen and wants a transfer away from the Merseyside. Although he would surely improve the Toffees upon his return, his contract expires at the end of the season. It might behoove Everton to sell him now instead of letting him walk for free.
