Manchester United manager Sir Alex Ferguson has explained that he re-jigged his defence for the game against Bolton Wanderers last night in part because he may have to do without Rio Ferdinand for the visit of Liverpool on Sunday.
Sir Alex Ferguson reshuffled the Manchester United defence for the 2-0 win over Bolton on Wednesday as a precautionary experiment in case centre-half Rio Ferdinand misses Sunday's titanic clash at home to Liverpool.
England defender Ferdinand is carrying a slight back injury ahead of the showdown with arch-rivals Liverpool, who will arrive at Old Trafford on the back of seven straight wins, with confidence sky-high.
Ferguson chose to rest Patrice Evra and Wes Brown against Bolton, fielding a defensive back-line comprising Owen Hargreaves, Nemanja Vidic, Gerard Pique and John O'Shea.
The manager told MUTV afterwards: "We made a lot of changes and I think that was necessary because, with Rio Ferdinand doubtful for Sunday, we had to find out about young Gerard Pique.
"We've got great confidence in the lad and he's come through very well. That was important. We also wanted to rest Wes Brown in case Rio doesn't make it, then we've got the alternative of playing Wes at centre-back â€“ that's a decision we'll have to make.
"We tried Owen Hargreaves at right-back, and we can play John O'Shea there on Sunday and bring Patrice Evra in. It's important to do these things tonight, simply because of Rio's injury."
