#2 Alexis Sanchez (Arsenal to Real Madrid)

Alexis Sanchez, whose contract with Arsenal ends in 2018, is yet to sign a new deal with the club. The Chilean does not intend to put pen to a new contract as he has decided to leave the London-based club. His will to leave the club was evident when he reportedly submitted a transfer request in the summer.
Arsenal could be losing their star attacker for free next summer if they do not sell him in January or make him sign a new contract. The latter does not seem possible as of now, so selling Sanchez in January would be the better option for the Gunners.
Manchester City, Sanchez's prime suitors in the summer, now have an attack that has fired them to the top of the Premier League table and they might not be coming back for the player.
A top team that has a struggling attack now is Real Madrid. The Los Blancos, who are eight points behind leaders Barcelona on the La Liga points table, have only scored 25 goals in 14 league games compared to the table leaders' 36.
Taking that into consideration, Real Madrid could be an ideal destination for Sanchez. The former Udinese player can make an immediate impact on Zinedine Zidane's team and get their season back on track.
Also, the fact that the 28-year-old is a former Barcelona player will make this an even more interesting move.
