Nemanja Matic was a disappointment in Manchester United’s loss to Arsenal upon his return from injury.
The theory behind his selection was smart.
Scott McTominay may have been tired after his Paris heroics, and £40 million man Matic was fresh and raring to go.
Unfortunately, a sharp if little tired McTominay was probably the better option than the fresh but out-of-sync Matic.
This causes a dilemma for manager Ole Gunnar Solskjaer for this weekend against Wolves which goes beyond choosing between Matic and McTominay.
More players are returning from injury.
Ander Herrera, Anthony Martial, Juan Mata and Jesse Lingard are all back in training and likely to be available for the FA Cup quarter-final.
In the case of Herrera and Lingard, they should be automatic starters.
However the trip to Molineux will be tough, and Matic’s performance highlights how tricky it is for injured players to slot straight back in and resume their high level of performance.
Martial may have got some of the rust off with his substitute appearance against Arsenal.
Lingard and Herrera are top professionals and will give everything out there on the pitch. Whether it is enough, is another matter.
Solskjaer could now be second guessing himself after Matic’s sluggish return, and opt to leave Lingard, Herrera and Martial on the bench.
It would be a dangerous gamble, but one which you could understand him taking.
