Tottenham travel to Manchester United on Sunday looking to build upon their 5-0 thumping of Swansea last time out.

Mauricio Pochettino’s side looked back to their best against Bob Bradley’s helpless Swans last weekend, and they backed that up with a fine 3-1 win over CSKA Moscow in the Champions League on Tuesday to seal a place in the Europa League.

This was all after they lost their unbeaten start to the Premier League season at Chelsea a fortnight ago, and only won once in their five league games before the trip to Stamford Bridge.

Nonetheless, Spurs have once again proven tough to break down, as they are the division’s lowest conceders with just ten goals against, and they’ll go into Sunday’s encounter at Old Trafford confident of picking up a third win in five games at the Theatre of Dreams.

However, although Spurs were unbeaten in the league up until November 26, they drew six times, and noticeably struggled creatively at times to get past opposition defences.

Some players have not been good enough so far for Pochettino’s side, and here are TWO players that need to improve over the coming weeks…

Moussa Sissoko

Many eyebrows were raised when Tottenham brought Moussa Sissoko to White Hart Lane in the summer, and it’s fair to say that those doubters haven’t really been proved wrong by the French international.

The midfielder has made seven Premier League appearances for Spurs so far, and has no goals and just one assist to show for it.

He has also hit the target just once from six attempts so far, and has created just ten chances, which is well down on the rest of the Tottenham attackers.

Sissoko improved in their win over Swansea last weekend, setting up Christian Eriksen’s second goal, but more is needed against the better sides from the 27-year-old, especially as Spurs lack a bit of depth in the attacking areas.

Vincent Janssen

Harry Kane’s spell on the sidelines gave summer signing Vincent Janssen the chance to prove his worth to Pochettino.

But he didn’t fare brilliantly up top for Spurs.

He started three Premier League games in place of the injured Kane, which says something about Pochettino’s trust in the Dutchman given Kane missed five league games, with Son Heung-min deputising in the other two.

However, Janssen managed just one goal in Kane’s absence, a penalty against Leicester, and is still yet to net from open play in the Premier League in 13 appearances.

The forward has missed the target more often than hitting it, and he’s created as many chances as Kane, despite making four appearances more.

Clearly, Janssen must improve when he deputises in the squad, as Spurs cannot keep relying on Kane. If he does get injured again or suspended, Pochettino needs strength in that department and, at the moment, Janssen isn’t giving him a trustworthy alternative.
