#2 Anthony Martial: Manchester United
Anthony Martial will be the source of some of the hottest transfer gossip this window. The Manchester United winger is rumoured to have fallen out of favour with Jose Mourinho, which resulted in him having lesser minutes on the pitch last season. This lack of time is attributed to be one of the biggest reasons for Martial's lack of inclusion in France's 2018 World Cup squad. If Martial does end up leaving United, it would be a perfect marriage for him to link up with Spurs.
Tottenham have two real players on the left-wing, and one of them has been the misfiring Georges-Kevin N'koudou who spent the latter half of last season on loan at Burnley, but not playing any real part in the Clarets historic Europa League qualification. However, they do have Son-Heung Min in that role.
Considering how talented Son is, he tends to move all over the front-line, usually filling in for Harry Kane as a striker. Martial is a lot like that, being able to play any place across the front-line, either playing on the wing or up front. Considering how talented he is, Martial could be the perfect signing for Tottenham this season, and the key for Tottenham's possible title run.
