#9 Harry Kane (-4)
Harry Kane had a largely disappointing month of January. He suffered an ankle ligament injury in the dying embers of the game against Manchester United - a game that Spurs lost at home but it wasn't for a lack of effort from their side.
Kane is scheduled to return in March even though there are claims that he could make his comeback well before schedule. However, he has dropped 4 places in the rankings and now sits at 9th having scored 2 goals and bagged a singular assist from 3 games. But in his defence, he could have retained his spot had he been fully fit in January.
But the world leaves you behind if you slow down, doesn't it? And for that reason, Kane will have a difficult climb back to the top when he regains full fitness.
