Why Mauricio Pochettino should keep Mousa Dembele at Tottenham Hotspur

Tottenham Hotspur are said to be sanctioning a deal to allow Mousa Dembele to join Napoli.

According to a report on TalkSPORT, Tottenham Hotspur are set to sell Mousa Dembele to Napoli for just over £10 million in January, but sanctioning such a deal could be a rare error by Mauricio Pochettino

Tottenham have worked hard to improve their success rate in the transfer window, and they have made some bargain buys over recent transfer windows - with Eric Dier and Dele Alli, two of their standout purchases.

However, allowing Dembele could be one of the first transfer window mistakes that Pochettino has made since arriving at White Hart Lane.

Dembele's story ever since arriving at Spurs has been one of much promise, but the Belgian has never quite managed to find a level of consistency to his game to make him a first-choice at the club. 

The 27-year-old had a wonderful spell towards the backend of last campaign where he was in sparkling form, but he lost his place in March 2015, and he has never been able to win it back.

Dembele has played just five times for Tottenham this season, but letting him leave the club would be a huge risk, as it could leave Spurs short of options.

Tottenham's defensive midfield has been built around Eric Dier and Dele Alli this season, but it reasonable to expect that both could hit a dip in form, given their lack of experience and age. 

Spurs do have Ryan Mason and Nabil Bentaleb also in reserve, but the former is has a track record of being injury prone, and the latter is still learning his trade. 

Without Dembele, Pochettino's options, therefore, could be limited in that position, and he could also leave himself short in the number 10 role.

Tottenham generally rely on Christian Eriksen to play behind Harry Kane up-front, but beyond that is there a better option in their squad than Dembele? Some may point towards Alex Pritchard, but he is not proven beyond Championship level, while Heung-Min Son, who can also play there, prefers to be deployed out wide. 

Dembele, though, has proven that he is an able supplier of the forwards, and he has an abundance of creativity.

Even though he has not made much of an impact this season, to lose Dembele's skill would have to be seen as a blow for Spurs, and to allow him to join Napoli could be seen as a mistake.
