Manchester United boss Louis van Gaal has insisted that his summer signings need time to settle at the club.
As reported by the Daily Mail, the Old Trafford chief, who was speaking to reporters ahead of the club's Premier League clash with Newcastle United tomorrow evening, has suggested that it's 'always difficult' for players to adapt in their debut seasons.
The Red Devils, of course, splashed the cash this past summer, but a number of their new stars have failed to hit their best form for the club.
Di Maria, who became United's club record signing, has endured a tricky period of late, and was even substituted at half-time as the Red Devils hosted Premier League strugglers Sunderland this past weekend, however Van Gaal has backed him to come good at the club in the long run.
In fact, the Red Devils chief has insisted that it could take as long as one year for his new players to really hit the ground running at the Theatre of Dreams.
When discussing his new signings, Van Gaal told reporters: "I think it counts for all the players that we have bought, the first season is always difficult.
"I have explained that in the press conference after the match. You can see it for every player we have bought, Luke Shaw, Daley Blind, Ander Herrera, Radamel Falcao and also Di Maria.
"For me it is not a big surprise. It is more a big surprise when he adapted as quickly as possible.
"In Holland, Spain and Germany, I had the same experience with players. We have to give him time, not just Di Maria but all the players. We wait and see.
"The general answer is one year, but you can't give a general answer. It is easy to say that, I cannot prove that. It is not scientifically proven."
There's no doubt about it, the array of talent that was purchased last summer has yet to really hit it off at Old Trafford, but Red Devils fans will no doubt feel confident that the players will eventually prove their credentials.
United need them now
Van Gaal is probably right. United fans won't see the best of Di Maria and Co. until the next campaign, but their stars certainly have to show signs of progression over the coming weeks and months of this season.
If the fail to deliver, then United may well miss out on Champions League football for next season, which would come as a major blow to the club.
Despite their struggles, the likes of Di Maria, Herrera are good enough to produce the goods for the club in the near future, and they will no doubt have a key role to play before the end of the campaign. United need them in the future, but they also need them immediately.
