Martinez is close to securing European football in his maiden term in charge of the Toffees, though it remains to be seen if they will qualify for the Champions League or Europa League.

And the former Wigan manager admits he will need to be busy when the transfer window reopens, with loanees Romelu Lukaku, Gerard Deulofeu, Gareth Barry and Lacina Traore all departing Goodison Park at the end of the season.

"It's not about improving - it's about increasing," Martinez said. "When you're playing in Europe you need to have another six or seven and that's the reality and we will do that - it's not an issue.
