My biggest disappointment was the complete lack of ambition in the first half, standing off city allowing them to play as they wish, passing sideways and backwards on the rare occasions we had the ball. Countless free kicks in both first and second half, either just in side our half or in their half, were just passed back to the centre halves or finished up with Lloris. Bearing this in mind, it was difficult to know if Kane was fit or not as he had virtually no service. Agree with others that Mason got the subs seriously wrong. No need to take off both Moura and Lo Celso as we needed their creativity and energy and Sissoko should have been nowhere near the pitch, contributing nothing other than his usual failure to mark a player from a corner for their goal. The game was tailor made for Lamela's energy and pressing and we needed Ndombele to help us keep the ball.
On a side note, that must have been one of the worse ref's performances in a cup final. He missed so many of City's fouls and his failure to book the 2 central defenders for their first professional fouls ultimately had a major influence on the game. He just looked scared to make a decision throughout.
