Ronald Koeman hailed the “incredible” Oumar Niasse after the striker emerged as Everton's unlikely hero against Bournemouth.

With the Blues trailing, Niasse came off the bench after 55 minutes and scored twice to turn the game on its head and earn a 2-1 Premier League win at Goodison.

They were the former outcast's first Premier League goals for the club 20 months after signing for £13.5million from Lokomotiv Moscow, and came just three days after he opened his account for the club as a substitute in the League Cup win over Sunderland.

Niasse is now Everton's joint leading goalscorer and Koeman believes the 27-year-old has more to come.

“Oumar was incredible,” said the Blues boss. “He came on and it was better for Dominic (Calvert-Lewin) to have somebody around him.

“He hasn't surprised me because I know him.

“Last season was a total different situation with (Romelu) Lukaku. We did not sign a striker and we have two strikers, Sandro who is 21 and Dominic who is 20.

“That gave Oumar a chance wto be closer to the first team.

“The boy has the kind of qualities when we are struggling, with his aggression and his direct play, he can create a lot of problems.

“For the first goal, he won the ball defensively, he made the one-two and it was a great goal.

“Nobody can stop him at the moment. He did well and all credit to the player.”

Asked if Niasse could now play a bigger part for Everton this season, Koeman added: “Of course he can. It's about opportunities for players, and about productivity if you speak about strikers.

“He came on last Wednesday and scored a goal. He came on (this time) for longer than Wednesday and he was one of the players who turned it around to get the win.

“The way how we did it is sometimes necessary. You can't always play the same way. It's a big quality of the team if you can change the style. That means we need to play with two strikers.”
