Manchester United manager Sir Alex Ferguson believes Liverpool have taken a gamble in signing striker Daniel Sturridge.
The 23-year-old, capped four times for England, has yet to assert himself in the Premier League, having played for three different clubs before his £12million switch from Chelsea earlier this month.
"The big issue for Liverpool is whether they include new signing Daniel Sturridge," Ferguson told United Review.
"Certainly the arrival of Sturridge gives Brendan Rodgers more strength and options up front.
"Sturridge has had a few clubs but I don't blame him for jumping at the chance of joining Liverpool because he just wasn't playing regularly with Chelsea and I always rate a player whose priority is wanting to play.
"Even so, his track record moving between a number of clubs suggests Brendan Rodgers is taking a bit of a gamble, but he clearly knows what he is doing."
Sturridge could start alongside Luis Suarez when the Reds tackle the Red Devils at Old Trafford on Sunday.
