Everton manager Roberto Martinez has made it clear to Manchester United, Chelsea or any other potential suitors that Ross Barkley is not for sale in January, even if they are prepared to break the world transfer record.

Barkley has enjoyed a breakthrough season at Goodison Park with Roberto Martinez at the helm, playing consistently in an advanced midfield role and impressing a whole host of new admirers across the continent.

Manchester United boss David Moyes is well aware of Barkley's raw potential after working with him during his Everton tenure, but Martinez is adamant that he would not consider parting with his most prized starlet despite rumoured interest from the Premier League's big guns.

Martinez even insisted that a bid matching the £86m Real Madrid paid for Gareth Bale would still not be enough to change his mind.

The Toffees boss told The Sun: "Ross is in a moment of his career where first, he knows that he needs to carry on developing and this is the perfect place to do that.

"Second, he is a mad Evertonian and enjoying every single moment. Third, we are in the middle of a season where we would never consider disrupting what we have in our squad now.

"It’s not the right time for the player or the club to consider anything. Even if we got a Gareth Bale-size valuation we would never consider it in January.

"Ross is an icon for us. He represents everything we are trying to do this season. It’s important for us to show we’re making the right football decisions."

The 20-year-old has been the driving force behind Everton's continued push for a Champions League spot this season, which continued with his third goal of the season from a free kick in a 2-1 win at Swansea City last weekend.
