James Collins, Stephen Warnock Sunderland switch in doubt?

James Collins and Stephen Warnock's move to Sunderland looks to be in doubt after the duo were named on the bench for Aston Villa's pre-season match against Chicago Fire.

The duo were reported to have signed a deal with the Black Cats on Sunday.

However, they both warmed up out on the pitch at Toyota Park before the match against the MLS side.

The Midlands club are currently in the States on a three-game tour.
