Manchester United striker Wayne Rooney has hit back at criticism of the club following their 5-3 defeat against Leicester on Sunday.
The Red Devils appeared to be cruising to a second consecutive win at the King Power stadium, with goals from Robin van Persie, Angel di Maria and Ander Herrera moving them into a 3-1 lead after 60 minutes.
However it all fell apart after full-back Rafael was adjudged, somewhat harshly, to have fouled Jamie Vardy after 62 minutes, and after Davide Nugent converted the spot-kick Leicester fired home three unanswered goals to ensure the Red Devils lost a game after having established a two-goal advantage for the first time in Premier League history.
The defeat means that Manchester United now have just five points from their first five league games, while they have claimed just one competitive victory since boss Louis van Gaal took charge in the summer.
They face a crucial encounter against West Ham at the weekend, and Rooney insists that the quality Van Gaal can call upon means they will come good sooner rather than later.
He wrote on his official Facebook page: "There seems to be a lot of people who have written us off because of Sundays result but I don't see it that way.
"When I look around our dressing room and see the quality we have and the managers unbelievable attention to detail I have no doubts this team will be successful."
Rooney started the game against Leicester playing behind fellow front-man Robin van Persie, who was alongside new arrival Radamel Falcao.
Falcao teed up Van Persie for the game's opener while Rooney had a hand in Di Maria's superb second goal. Despite making a telling contribution to the game, Van Gaal has suggested that Rooney may be moved about in order to maximise his side's attacking potential.
The Dutch boss said: "Rooney can play in more positions, he's a multifunctional player and I have tried him in a striker's position. He has played well, but not spectacular. Falcao is a striker and I think he can do it better."
The England international agreed with his manager's assessment, and believes he has much more to offer Manchester United as his career progresses than just scoring goals.
"I'm not the player I was," the 28-year-old said. "But I feel I have progressed my game. I agree with the people who say my game has changed. I did too much running when I was younger and then didn't have the energy to get myself into goalscoring positions in the box.
"I'm a cleverer player now and know when to run into the box and when not to, and as a result more chances have come my way and I've scored a lot more goals for the club.
"But I am happy to play out wide. I can do a job there and I can do a job up front. It depends on the situation of each game and what the manager wants me to do. I don't think anyone can put a finger on my best position, but I am adaptable."
Manchester United will have the chance to bounce back from the defeat against Leicester when they take on West Ham at Old Trafford on Saturday.
