Arsenal may have injury challenges this season but they have not suffered in attack with Giroud and Welbeck, available and Sanchez in the form of his life. Sadly that leaves players like Campbell and Sanogo out in the cold.
Wenger has decided to let Yaya Sanogo out on loan in January so the player can gain first team experience outside the club. Wenger would prefer to loan him to a premier league club and Crystal Palace are rumored to be interested in the player. Sunderland also have a vested interest in the player and so do a few French teams
Sanogo would benefit from the experience and he would definitely be an asset to any team he koins at this stage of the season
