Manchester United manager Jose Mourinho has been burdened by the players Louis van Gaal's brought to the club, according to Red Devils legend Gary Neville.
Mourinho has publicly expressed his disappointment at the club's transfer window, with only three players arriving at Old Trafford.
Neville told Sky Sports: "It hasn't gone well, but you've got to remember Jose Mourinho has spent a lot of money, but the Louis van Gaal signings I have to say were really poor.
"So Jose Mourinho has had to get out of the club seven, eight, nine, 10 players, and then get them in.
"He's only been here two years, he's not been here 15 years.
"So for me there is still more investment to do to make up for the mistakes in those first three or four seasons.
"I actually like the signings Jose Mourinho has made, they're more along the lines of the players I'd like to see at this football club."
