3 reasons why Manchester United lost 0-3 to Tottenham

#3 Substitutes fail to make the desired impact

Lindelof looked shaky after coming on in the second half

Tottenham Hotspur turned on the heat in the second half after goals from Harry Kane and Lucas Moura gave them an unassailable 2-0 lead in the 54th minute.

In order to get back in the game, Mourinho immediately brought on Alexis Sanchez, who replaced Ander Herrera shortly after the second goal. Herrera was caught out of position on several occasions during the game and was also responsible for not closing down Moura in the build up to the second goal.

Along with Sanchez, Mourinho hauled off Phil Jones and Nemanja Matic for Victor Lindelof and Marouane Fellaini respectively.

The introduction of Sanchez looked to inject some energy during the initial stages of the second half, but the Chilean looked clueless while picking out a pass in the final third. Fellaini replaced Matic in the 61st minute and cut an anonymous figure during his cameo as the Belgian was well marshalled by Alderweireld and Vertonghen, and did not receive enough deliveries from his wingers and attacking midfielders.

On the other hand, Lindelof seemed to have been reeling from the after effects of the game against Brighton and did nothing to transmit calm across the back line. An example of this was seen in the 66th minute after his atrocious back pass found Dele Alli, who's attempt was saved by David De Gea.

Overall, the substitutes could not offer their side a route back into the game which leaves Mourinho and Co. with much to ponder about.
