Manchester United striker Robin van Persie has revealed that coach Louis van Gaal held an emergency meeting following their dramatic 5-3 defeat against Leicester City last weekend.

Manchester United was ahead by 3-1 till the 60th minute of the game against Leicester but they conceded 4 goals in last 30 minutes to lose the game by 5-3. Van Persie said that an hour long meeting headed by Louis van Gaal focused on the defensive errors that allowed Leicester City to come back strongly at King Power Stadium.

“It shouldn’t be possible,” Robin van Persie told Fox Sports News. “But it still happened. We have to deal with it. We had a proper look at it next day. Sometimes it was a bit confronting and it was a long meeting. One hour [or] something.

“We went from there, started again this week [and have put] a couple of really good sessions in. Everyone feels ready to face West Ham.”

Manchester United spent more than 150 million pounds on new signings like Radamel Falcao, Angel Di Maria, Daley Blind, Ander Herrera and Luke Shaw this summer but they failed to sign any specialist central defender. And Van Persie feels that current defenders like Phil Jones and Jonny Evans will have to improve their game and avoid mistakes.

“When you look at the defensive mistakes, it starts somewhere else,” Van Persie said. “That’s where we looked at as well. It’s not just the one mistake which happens. There’s a mistake before the mistake and before the mistake, maybe positional wise. Everyone knows where we have to improve.”

Meanwhile, Manchester United boss Louis van Gaal has said that this is the hardest moment of his glittering managerial career. Manchester United failed to qualify for Europe this term and the Dutchman is aware of the high expectations.

“As a manager you know in advance it’s a big challenge and the club is in a transition but you don’t know in advance the difficult moments,” Van Gaal said.

Manchester United have failed to make a positive start to their campaign so far but Van Gaal stressed that there is no panic at the club. Van Gaal said: “I have to admit I’m never in this situation before so that’s strange.

“For me it’s difficult to understand because we are evaluating what we can do in a different way but you have to train on a certain level. We have a lot of injuries, nine injuries now, and Blackett suspended. So that means that 10 are off so I have to go to the youth team to pick players.”
