Manchester United manager Louis van Gaal has admitted that he may have to make changes to the centre of his midfield to make it more physical.
The Red Devils needed a stoppage-time equaliser from Daley Blind to earn a 1-1 draw away at West Ham United on Sunday.
The Dutchman believes that his creative players are not capable of winning the ball back, unlike Marouane Fellaini.
"We need the guts to play football along the floor. That we have done in the second half," Van Gaal told ITV Sport.
"With [Fellaini] we have more power. With Adnan [Januzaj] and [Angel] Di Maria, we have more creative players. The second ball you cannot always win with these players.
"But you have to win [the ball], otherwise I have to line-up always [with] players like Fellaini."
United are fourth in the Premier League following the result.
