Louis van Gaal says he "feels" Manchester United assistant boss Ryan Giggs will become the next boss at Old Trafford and has admitted to being "sickened" by criticism from former players Gary Neville and Paul Scholes.

Speaking to an audience of executive United season ticket holders at Lancashire County Cricket ground on Wednesday night, van Gaal said he was delighted to have Giggs working as his right-hand man. Van Gaal said after a meeting with the former Wales winger, in which Giggs gave his assessment of every player in the United squad, he was more than happy to keep the United legend on the Old Trafford payroll.

"I feel I am introducing the next manager of Manchester United," said van Gaal, who also revealed he was well aware he had paid well over the odds for 19-year-old striker Anthony Martial. It was a ridiculous amount of money, but it's the crazy world we are in.

"United are routinely quoted $15 million more for a player but I have not bought Martial for me. I have bought him for the next manager of Manchester United, " said van Gaal, who paid an initial $55 million for the Monaco striker, which could eventually rise to around $89 million.

The United boss was also asked what he thought of the criticism aimed at his side's performances by ex-United pair Scholes and Neville and added: "It makes me sick because they should know that it takes time."
