Celta Vigo's players have been given a taste of the Old Trafford pitch that will host their Europa League semi-final second leg on Thursday evening.
Iago Aspas, John Guidetti and Co trained in Manchester 24 hours before their match against United, which has been billed as the biggest in most of the players' careers.
It will be an uphill battle for Celta after their 1-0 defeat in the first leg, but the players will be confident they can give themselves a chance of achieving the unlikely.
The players underwent a light session on the Old Trafford turf in the early evening, before gathering for a huddle with manager Eduardo Berizzo.
