Ruud van Nistelrooy admits the bitter disappointment of leaving Manchester United and is still grateful to Amorim! Again to make his Premier League debut

Ruud van Nistelrooy will make his Premier League debut again on Tuesday and has already officially taken over as Leicester City manager, starting with a home game against West Ham United. The 48-year-old admits he was hurt and disappointed after being sacked by United last month.

Ruud van Nistelrooy is a Manchester United legend with 150 goals and three wins and one draw in four games in charge, however, the Dutchman is still out of the coaching staff of new boss Ruben Amorim, who brought his own six-man team without Ruud van Nistelrooy.

On his first day as Leicester City boss, Ruud van Nistelrooy confirmed he had held talks with Amorim and admitted he had been sacked because his presence could cause problems for the 39-year-old Portuguese manager. 'I said when I took over as interim manager that I would come here to help Manchester United and that I would stay and help Manchester United and I meant it. So I'm disappointed, very disappointed, and it's sad for me to have to leave." Vanney said.

He explained: "The only team I'm willing to work as an assistant coach is at Manchester United because I have developed a great friendship with the people in the club and the fans. In the end, I accepted it because I understood the new manager. I've been a manager myself and you can imagine a situation where if I stay at Manchester United [it could be a problem]...... I understand."

Ruud van Nistelrooy thanked Amorim for his frankness: "I spoke to Ruben [Amorim] about it and he was very frank and I am grateful for the conversation, which was between men and men, between men and men, between managers and managers. It helped me a lot and got me moving on and getting straight to talking about potential new jobs, which certainly lifted my spirits."

Having played for the likes of Lord Fernandes, Sir Bobby Robson and Fabio Capello, as well as players and coaches at Old Trafford, Ruud van Nistelrooy knows how to manage a team and now needs to use that experience to master Leicester's chaotic dressing room.

It's like Amorim at Manchester United, or a new teacher taking over a disobedient class. Ruud van Nistelrooy said he would not hesitate to let the Leicester players know who the real boss is. British media revealed that when the former coach Steve Cooper got out of class, the Blue Foxes players actually had a party to celebrate, and also said that they missed the former coach Enzo Maresca.

Leicester City have strong players, but Ruud van Nistelrooy knows captain Jamie Vardy, who has been congratulated by the Dutch legend when he broke Ruud van Nistelrooy's record of 10 consecutive wins for United with 11 consecutive goals. Asked how important it is for players to respect the manager, Ruud van Nistelrooy said: "It's the only thing players can do, to respect each other. I also mentioned to the players that I looked at the squad and started calling to ask about the players because in football, everybody knows everybody. Two or three phone calls to hear the stories of 20 players, and for me, it's important to hear that they're all good people. I would watch the players and obviously I don't know them yet, but I got some general information about them personally, they are a good bunch."

Another problem for Ruud van Nistelrooy is that he not only needs to keep a close eye on the team, but also has to deal effectively with the club's hierarchy. Under the leadership of the Srivadana Brapa family, Leicester City have miraculously won the Premier League, FA Cup and Community Shield, reaching the quarter-finals of the Champions League and the semi-finals of the Europa League. However, that was already a glorious old day, and in recent seasons there have been problems with the club's management and fans complaining. Now, both the management and the players need to do their best to help Ruud van Nistelrooy succeed.

When Leicester City suffered a 4-1 defeat at Brentford under their interim manager last weekend, fans were already clamoring for a buy in the January window. "I think the management of the team is successful, but it needs to be guided, it's my responsibility and I need to know who the leaders are. I need to talk to them about how management works, and I need the best managers to guide me through the various stages of my career. I'm very fortunate to have these managers to help me coach the way I want."
