Manchester United manager Sir Alex Ferguson has praised the impact of Javier Hernandez after the Mexican scored the winner against Braga on Tuesday night.

Ferguson also admitted that with the attacking talent at his disposal he has struggled to fit Hernandez into his lineups.

"He is improving all the time," BBC Sport quotes Ferguson as saying. "He trains magnificently and he has great enthusiasm.

"I must say he has got me thinking. I have got him, Wayne Rooney, Robin van Persie and Danny Welbeck, and I don't know what to do with them."

United currently top Group H with maximum points from their first three games.
