Former Manchester United captain Gary Neville believes that it is 'unrealistic' to suggest that Louis van Gaal will guide the Red Devils to Premier League glory this season.

The North-West outfit finished seventh under ex-manager David Moyes in the 2013-14 campaign, but expectations have been raised following the arrival of former Netherlands boss Van Gaal.

The club have acquired the signatures of midfielder Ander Herrera and left-back Luke Shaw this summer, but Neville believes that United need a few more additions in order to launch a title bid.

"Unless two or three players come in I don't think it's realistic that he can win the league this year," Neville told Sky Sports News.

"Although there is a potential with what Liverpool did in the fact they had free weeks of Saturday to Saturday, continual perfect preparation. That's a big advantage for United if they get onto some momentum."

United will begin the new season with a clash against Swansea City at Old Trafford on Saturday.
