Yaya Sanogo has bagged a hat-trick for Charlton! WAKE ME UP, BEFORE SANOGO2016-2-27 16:52:53
The Frenchman, who joined the Championship strugglers on deadline day, struck an early equaliser, before leading Charlton's fightback from 3-1 down to level the scores in the 84th minute.
His hard work was undone by Deniss Rakels' dramatic, last-minute winner, but that didn't stop Gunners fans going positively crazy as news filtered through of their latest hero's exploits.

The absolute banter when we recall Sanogo from Charlton, he does a Coquelin and subsequently goes on to win the Ballon d'Or.2016-2-27 15:12:29
