"I like him a lot" - Wolves boss impressed with summer signing's start

Wolves signed the Czech international on an initial loan deal, which will become permanent next summer, for a total package worth £26million.

He has played in several different positions and formations across midfield and defence in just four Wolves appearances and has already become a key member of the starting XI.

And the head coach is delighted with the start he has made in the Premier League.

"Krejci is a technical player, with experience, who makes good decisions with the ball with maturity," Pereira said.

"He's a player with high quality and he can help us as a midfielder and as a centre-back.

"He has experience. I knew him from Sparta Prague, he was captain of his team at 21 or 22-years-old and he's a national team player. I like him a lot.

"Krejci is an intelligent player, a technical player with the left foot.

"He has quality and he understands the game because he has experience.

"He can play as a defender on the left or the middle, or he can play as a midfielder.

"It means when I say to you we must find solutions inside the squad, he gives us the chance to play in different positions and he's the kind of player that's important for a team."

In each position and formation that Krejci has played in, the 26-year-old has impressed.

But when asked if he would prefer to settle Krejci into one position, Pereira said: "Yes, but we didn't get a midfielder and we need to find solutions.

"We need players to play in more than one position in this moment.

"If we need a midfielder, he can play there, if we need a centre-back, he can play there. He's a player that gives us a lot."

Meanwhile, Pereira has backed starlet Mateus Mane to play at the highest level but insists he needs time to improve.

The forward, who turned 18-years-old last month, got his senior team breakthrough under Pereira last season before joining them for the pre-season camp in Portugal and Spain.

Mane also signed his first professional contract but has yet to play this season and has instead played regularly for the under-21s.

Pereira still has faith that Mane has a big future, but has urged patience as he develops.

"The conversation between me and him is that he will be with us in training and physically he must do a lot of work for the Premier League," Pereira said.

"We'll see, I think he has skills for the top level but he's young and he needs to work to improve."
