Bayern Munich winger Arjen Robben hopes that Manchester United give Louis van Gaal time to succeed at Old Trafford, but fears that might not be the case.
The Netherlands international, who flourished under Van Gaal's management at this summer's World Cup finals in Brazil and was signed by the veteran Dutch coach for Bayern Munich in 2009, was quoted by De Telegraaf as saying: "I hope they'll give him time. But in England, that's often not the case."
Robben admitted that Tuesday night's shock 4-0 defeat to League One side MK Dons in the Capital One Cup was a "big" result, but added: "If you look at the history of Van Gaal's clubs, you actually see the same: he needs time.
"United is not exactly a team with a lot of confidence at the moment [and] Van Gaal has to totally rebuild after last season."
Van Gaal still looking for first win
Van Gaal, who replaced David Moyes as Manchester United manager earlier this summer, is still looking for his first competitive victory as the Red Devils' head coach.
United currently sit 13th in the Premier League table following a 2-1 defeat to Swansea City and a 0-0 draw with Sunderland, and slumped to that humiliating 4-0 defeat at the stadium:mk earlier this week.
Van Gaal insisted he was not surprised by the result, which sent shockwaves across England, and reiterated that it was always going to take time for his players to familiarise themselves with the new system as well as his philosophy.
United chiefs want top-four finish
Manchester United chiefs have assigned Van Gaal the task of getting the club back into the Champions League at the first time of asking, but the Red Devils will face an uphill battle to secure a top-four finish unless their form quickly improves.
The Premier League giants take on newly-promoted Burnley on Saturday, with the club's new record-signing Angel di Maria eligible to make his debut, and nothing but a victory will satisfy the Red Devils' expectant supporters.
Van Gaal wants more signings by Monday
Van Gaal - along with United's executive vice-chairman Ed Woodward - are also under pressure to sign a new central midfielder and another centre-back before the summer transfer window closes on Monday night.
No English club have spent more money than Manchester United in the current transfer window - a total which currently stands at a cool £132 million - and the club's owners, the Glazer family, are expecting an instant return on their investment.
Prospective investors have been warned about the potential implications of United missing out on a top-four finish for the second consecutive season, with the possibility of the club losing not only their top players, but also their top coaching staff.
So unless Manchester United's form picks up, questions may soon be asked about Van Gaal's suitability for the job.
