He said: "We are now in the Champions League and we need something more to play against the big teams. Now he knows very well what I want and my expectations are higher. Not only for Riyad but for all my players.
"I was so sure (he would stay), it was only speculation with first Vardy and then Mahrez and we only lost (N'Golo) Kante. Now it's important to stay together.
"We spoke together last season and in pre-season and he told me he wanted to stay. Speculation is normal.
"I want to keep our big players, that's normal. Our owner is very ambitious, he wants to maintain the same squad. It's normal other managers are looking at Leicester players, there's no message - we are building and want to stay together.
"He signed for four years, me too because I want to build. He wants to build something, Jamie wants to, Kasper (Schmeichel), everybody. It is good."
