Everton boss Frank Lampard hailed the impact of Dele Alli after victory over Crystal Palace.

The win sees Everton secure Premier League safety.

Lampard said of Alli: "He had a massive role. We brought him to the club after a tough time. I'll be honest sometimes it's like we have to wait for you, can you train better? Can you fight to make me play you? Absolute credit to him today to suck it up sometimes. He has so much talent there. What he did was come on with quality, with belief, with legs and energy. He changed the game."

On Michael Keane's goal, he added: "It was crucial because we needed it at that time, we needed belief. Michael is one of the best finishers at the club – people won't believe me."

On Dominic Calvert-Lewin's winning goal, Lampard declared: "Dominic was immense, he was the other day against Brentford. He hasn't been fully fit, he has been fighting back from injuries – people want to comment on that and ask questions because he is a top player. He played like a top player. It's right for him to score that goal because you get what you deserve in football and his work ethic and staying in the game, what he means to this club and I am delighted. Everything you want in a number nine."
