Moussa Sissoko cost Tottenham Hotspur £30 million in the summer.
Failing to score from open play in any of his 15 games for Tottenham Hotspur means that Vincent Janssen certainly has to improve.
Janssen, an £18.5 million signing from AZ Alkmaar in the summer, has three goals under his belt – all penalties – but there is another pre-season recruit with even more to prove.
In August, Tottenham spent a club-record £30 million on taking Moussa Sissoko from Newcastle United, but fast forward a few months and the Frenchman has done very little so far to justify being Spurs’ most expensive signing in history.

The 26-year-old winger has made nine appearances across Premier League and Champions League action – five of these were starts – but he is yet to score or even set up a goal for the out-of-form Lilywhites, without a win in eight games in all competitions.
He has hit the headlines, but only for his three-match retrospective ban after allegedly elbowing Bournemouth’s Harry Arter last month.
Such a hefty transfer fee demands productivity in the form of goals or assists and the fact of the matter is that Sissoko simply has not provided any of either so far.

He managed one goal and seven assists in 37 Premier League games for Newcastle last season; stats which did little to help the Magpies in their relegation battle.
But a much-improved Sissoko turned up to Euro 2016 with France and played a big role in helping Les Bleus reach the final, where they were defeated by Portugal.
It certainly surprised Newcastle fans, many of whom wondered where that version of the Frenchman had been over the previous nine months, and the worry for Tottenham supporters must be that he no longer has the same incentive to produce such barnstorming displays after already earning such a big move on the back of it.
