Manchester United are not making the most of Shinji Kagawa's ability, according to former Red Devils defender Henning Berg.
Kagawa has started five of United's six games this season, but Berg believes his team-mates need to trust him more.
"I was very impressed with Kagawa [against Galatasaray]. He looks a top player and is a real bundle of energy," he told talkSPORT.
"His positional play in that role gives Manchester United something extra. They’ve not had someone in that role before.
"The only thing missing is someone to score all the chances he makes.
"Kagawa gives Manchester United an extra dimension. His positional sense is excellent both offensively and defensively.
"He’s always available to get on the ball. It’s easy for Paul Scholes and Michael Carrick to find him.
"In the past when United didn't have the ball they have struggled in Europe. They’ve been over-run by other teams.
"The way he defends in front of the two central midfield players makes it so much easier for the team though."
