Manchester United boss Ole Gunnar Solskjaer has offered more details on what he wants from any summer signing.
Solskjaer says any signings United make this summer must fit the culture and history of the club.
"You have to have a certain kind of attitude about you to make you a Manchester United player," Solskjaer told United's official app. "You have got to have the qualities and our fans want to see exciting players.
"Of course we want to get up from our seats. We want to see defenders who defend like they're doing it for their lives, that's the most important thing.
"We've tried to educate our players and our kids to be proper people. In my view, the best players have always been the best people.
"It's always been in our culture. You have to have that work ethic and we're scouting the market, trying to find the right ones."
