10 Best Premier League January Transfer Window Signings Of The Decade
4. Dele Alli - Spurs
There can be little argument that in terms of value for money, that Dele Alli is one of the best signings of the last decade.
Alli signed for Spurs during January of 2015 before being immediately loaned back to MK Dons before Spurs thrust him into Premier League action.
At just £5m, Alli has proven a complete snip for Spurs. Goals have flowed for the attacking midfielder and up until recently, he'd become an integral part of the England set up.
A slight loss of form last season has seen questions start to come to light over Alli's commitment to the cause.
However, the recent appointment of Jose Mourinho seems to have rejuvenated Alli. The only thing missing for the attacking midfielder is a trophy. But as part of a Spurs team who has failed to capture any silverware, Alli is not on his own in that boat.
Remarkably, Alli is still only 23 and could go on to get even better under the guidance of Mourinho.
