Manchester United manager Jose Mourinho: 'I don't know my best back four!'

After a 3-0 loss to Spurs on Monday night, the United boss accepted he was unsure about his side's best defence

Manchester United manager Jose Mourinho admits he is unsure what his best back four is after a tough start to the Premier League season.

Mourinho is under fire after United suffered a second loss in three league games with their 3-0 defeat to Tottenham at Old Trafford on Monday.

The Portuguese tactician is yet to start the same defence in any two games this campaign, with only left-back Luke Shaw starting all three matches and midfielder Ander Herrera used at centre-back against Spurs.
