Transfer news: Everton will not sell Leighton Baines or Ross Barkley during January window

Roberto Martinez insists that Everton will resist transfer bids for their top players during the transfer window.

David Moyes is considering making another attempt to sign the left-back Leighton Baines for Manchester United, having failed to bring him to Old Trafford in the summer, but, as revealed in Tuesday's Independent, is aware it will not be easy to convince his former club to sell .

Martinez has reinforced that point. "Yes, absolutely, there is not even a doubt," he said. "I have said it many times that in football you can't fight the trend of the game but what you can dictate is the timing and everything you do should be for the good of the club."

When asked about Barkley, he said: "£50m? No. He has a long-term contract and the first half of the season has been a real joy to see him grow and the second half of the season will be even better.

"The stability we have from a financial point of view allows us to make football decisions. This January window is important for us to make sure we kick on and finish the season stronger than how we have started it."
