Everton manager Ronald Koeman said his side had made costly mistakes after they were beaten 3-2 at Tottenham Hotspur on Sunday.
Harry Kane fired in from distance to put the home side ahead at the break and added a second after visiting keeper Joel Robles rolled the ball out to Morgan Schneiderlin, who was dispossessed.
Everton lost the run of midfielder Dele Alli, who flicked home the match-clinching third after a Harry Winks free kick was chipped into his path, with Romelu Lukaku and Enner Valencia the scorers for the visitors.
“We made some mistakes and if you make those kind, like the second and third goals, it was too easy,” Koeman told Sky Sports.
“We did well. We had some good counter-attacks but needed more composure on the ball.
“We had the chance to get a point but it was not deserved.”
Koeman added that he felt his side “showed good character” but said: “Overall, Tottenham were the stronger team.
“Tottenham have two or three years in a row with the same players. It’s all about time, which is what we need to have.
“If we get the time to improve, that’s the next step for the club.”
