Ander Herrera: Usually such a dependable player this season, but March has been a harsh lesson for the Basque player. It could be down to a loss of energy due to his high work rate but without that same tenacity he appears a different prospect, highlighted in the Rostov match at Old Trafford and against Chelsea. The red card against Chelsea could be deemed harsh but either way it cost United in an important game for his team and Mourinho as it appeared his tactics could allow his side to snatch a result.
