MF: Ander Herrera
Herrera had a positive impact in his first season in England last year, but he will hope to build on that and get straight back up to pace in pre-season.
MF: Memphis Depay
There is significant excitement around the Dutch winger, and he will hope to have an immediate impact to show what he can offer the Premier League giants.
MF: Juan Mata
Mata may not stay in the team by the time the season gets underway, but he is a creative force that could thrive playing out wide or behind Wayne Rooney.
FW: Wayne Rooney
Rooney will be tasked with scoring the goals to take United back to the top, unless Van Gaal moves for a striker. With Robin Van Persie no longer around, it will be down to the England ace to spearhead the attack.
