#3) Harry Kane
In Harry Kane, Mourinho has one of the best strikers in the world. Mourinho has always liked strong strikers leading his attack. Didier Drogba, Romelu Lukaku, Zlatan Ibrahimovic and Diego Costa have all performed exceedingly well under him before. Harry Kane is also a very traditional striker like the names mentioned before and could very well serve the Portuguese just like they did.
Both United and Tottenham enter this match with a very leaky defence. In the end, the match is very likely to be won by the side that attacks better. Man to man, Spurs have the far superior attacking front and in Harry Kane they have a great weapon that United lack; a clinical finisher.
Kane has already mentioned that the manager looks at him as a key player and it appears that he trusts his manager as well. There is nothing that the Portuguese can coach Kane. However, players like Kane need managers who allow them to express themselves.
Someone like Rooney perhaps would not have been the kind of player he eventually became without the guidance of Sir Alex Ferguson and that is the role Mourinho will have to play for Kane. If the Portuguese can make Kane fall in love with playing football for Spurs once again, a trophy is almost a certainty for the side in the near future; or at the very least, a victory against United on Wednesday.
