The worrying Defoe stat which proves he may not be right for Sunderland

Sunderland's newest recruit, Jermain Defoe, managed just one goal in 14 Premier League games in his last season in England with Tottenham Hotspur.

Sunderland's signing of Jermain Defoe is no guarantee that they will end their scoring problems. 

The Black Cats have struggled for goals this season - hitting the back of the net just 18 times in their first 21 Premier League matches - and Defoe has clearly been brought in to improve that tally during the second half of the season. 

Sunderland are in fear of the drop and their need for a clinical striker is obvious, given that the side have only managed to win three games to date this campaign.

It is a remarkably poor statistic, but Defoe's addition cannot be considered as a foolproof method of securing their safety in the Premier League.

The former Tottenham Hotspur striker is ageing now and there also have to be question marks over just how well he will fit into the defensive system that Sunderland play. 

Connor Wickham, Jozy Altidore and Steven Fletcher have all struggled plowing a lone furrow up front for Sunderland this season and Defoe is unlikely to fare any better, given his previous showings in the role.

Alongside a teammate, there can be no questioning that the England international is a threat. With the speed to spin off defenders and a unerring ability in front of goal, he remains one of the finest finishers the country has produced, but as a lone striker Defoe has previously struggled. 

His lack of strength and power mean that he is unable to hold the ball up, while his link-up play has always been a weakness, meaning others are not able to get into play. 

Added to this, Defoe has recently been playing in MLS and during his last year in England he already appeared to be off the pace - as he rather worryingly scored just once in 14 Premier League appearances. 

His time away is unlikely to have helped his match-sharpness, either, and if Sunderland are simply relying on Defoe to end their goalscoring woes all the signs suggest that they could end up disappointed with their purchase.
