Everton defender John Heitinga admits he misses European football and is ruling nothing out this summer.
The 27-year-old Holland international switched to Goodison Park in £6.2 million transfer from Atletico Madrid in 2009 and played 26 times for the Toffees last term.
While Heitinga still has three years left on his contract, he admits to a frustration in not playing European football.
He told The Sun: "I can honestly say I feel annoyed at having the day off when I'm on the couch watching Champions League football on Tuesdays or Wednesdays.
"It's the same on Thursdays with the Europa League. European football is a big miss for me.
"Everton is a genuine big people's club. The atmosphere at Goodison is unrivalled, and I'm playing in a fantastic league.
"But I am ruling nothing out this summer. I have three years left on my contract and could see it through - but a new possibility could come up.
"In that case I will think about leaving."
While Heitinga says former club Ajax is in his blood, he is not planning an immediate return to the newly-crowned Dutch champions.
He said: "Ajax are not on my agenda for now. They are my club for life and I will rejoin them some day but not now."
