Ronald Koeman has admitted he was frustrated when manager of Everton.

Koeman felt he could've achieved more with a bigger budget.

He said: "Everton is different because Everton tried. I was one and a half seasons at Everton, the first season we did well and ended sixth in the Premier League - maybe the best record in the last 15 years.

"It's difficult though because Everton had the money, but it's always difficult because if you try to sign good players or star players - if they can choose between Tottenham, City, Chelsea, Man United, Arsenal normally they will choose that kind of club and not Everton.

"Changing managers is not always the reason that it will be better. They are struggling in the last few years, fighting against relegation, and let's hope that they come back up in the table."
