Manchester United's players have become well accustomed to visits to Spain with Erik ten Hag in charge at Old Trafford.
United stayed over in San Sebastian after losing to Real Sociedad in the Europa League last month and they trained using Deportivo Alaves' facilities before flying back to Manchester.
The passports have been brought out again at Carrington this week and United have flown to Spain for another visit, with Ten Hag taking his side to a training camp, to prepare for friendlies against Cadiz on Wednesday and Real Betis on Saturday.
