BACK FOUR TO THE FUTURE

Shape shifter Amorim to keep new system

- BY TYRONE MARSHALL

MANCHESTER United's back four could be here to stay after Ruben Amorim insisted he wouldn't revert to a back three every week when players return from injury and international duty.Amorim switched shape for the first time as head coach in the Boxing Day win against Newcastle and could stick with it against Wolves.

After showing signs of flexibility for the first time in his 14 months in charge at Old Trafford, Amorim suggested a back four would be for life and not just Christmas, even when key men return over the next few weeks.
