Jamie Carragher: 'You worry about Manchester United in next round'

Former Liverpool defender Jamie Carragher believes that Manchester United will struggle in the next round of the Champions League.

The Red Devils, who qualified for the quarter-finals of the competition with a 3-2 aggregate victory over Olympiacos, have struggled domestically this season.

"You worry about them in the next round who they are going to come up against," Carragher, who won the trophy with Liverpool in 2005, told Sky Sports News. "Everyone will be hoping for United in the draw, I think so."

United could face Chelsea, Borussia Dortmund, Atletico Madrid, Barcelona, Bayern Munich, Real Madrid, or Paris Saint-Germain.
