Henrikh Mkhitaryan faces a challenge to win back a regular place at Manchester United after he was left out of the squad for the last two games.
The Armenia international was overlooked by Jose Mourinho for the Premier League win over Newcastle and Champions League defeat to Basle, and must convince the United manager that he deserves a recall.
With the Group A tie in Switzerland starting a run of 13 games in 40 days through until New Year, Mkhitaryan is bound to be given opportunities in the coming weeks as Mourinho makes the most of his squad.
