Everton manager Roberto Martinez has revealed that forward Apostolos Vellios has been refusing to go out on loan.

The Spaniard believes that the 21-year-old has "great potential", but needs to pick up some regular game time at a club elsewhere.

"As a long-term I see him with great potential but in the short-term he needs minutes," the Liverpool Echo quotes Martinez as saying.

"Going out on loan is something we're going to assess, but going down the line it comes down to if the player is open to do that, and in the past it doesn't seem like that was something he was ready to consider."

Vellios moved to Goodison Park from Iraklis in 2011.
