Most of Tottenham's headlines currently seem to be surrounding Harry Kane and the injury he sustained against Man United yesterday. 

The England captain twisted his ankle, and now Tottenham fans are nervously awaiting the verdict as to how serious the injury may be. Mauricio Pochettino must know that this injury could be one of the defining moments in Spurs' season.

However, while Kane has stolen the limelight, Moussa Sissoko's injury may have been forgotten. But this could be as dangerous as Kane's.

The Frenchman hobbled off in the first half at Wembley, looking to have pulled a muscle in his leg. Should this be a serious injury, Spurs could be in a lot of trouble.

With Mousa Dembélé's departure to China imminent, Victor Wanyama still out and Eric Dier coming back from injury, Spurs are only left with Harry Winks and novice Oliver Skipp in the midfield. The 18-year-old Skipp has been getting more and more exposure in the Premier League in recent weeks, but Pochettino will certainly not want to consistently rely on him in the heart of the midfield.

Of course Christian Eriksen can drop deeper in the midfield, as he did against Man United, but with Kane's potential absence, and Son Heung-min at the Asian Cup, The Lilywhites still need bodies further up the field. This also makes Tottenham very weak defensively in the middle of the pitch.

Spurs will hope that Sissoko's injury is not as bad as first thought, otherwise, they will need to remedy the problem very quickly, and the transfer market may be the only way.
