Liverpool legend Jamie Carragher has applauded Manchester United's central defensive pairing of Chris Smalling and Daley Blind.

United manager Louis van Gaal has shifted Blind from left fullback and defensive midfield to the centre of defence this season, with the Dutchman seemingly adapting well to the change.

Speaking on Sky Sports News, Carragher complimented the cohesion and efficiency displayed by Smalling and Blind during the early rounds of the Premier League season with the Red Devils yet to concede a goal in three fixtures.

"The work that has been done on the training ground with Chris Smalling and Daley Blind has helped," Carragher said.

"They've looked a very good partnership, even though there were question marks over Blind playing there. They've looked strong and secure."
