Former Everton defender Martin Keown has urged John Stones to stay at Goodison Park.

Stones has been the subject of two offers from Chelsea over the past week.

Keown told 888sport.com: "'I think it's very early days. He's only really had one season in the Premier League and he hasn't yet become a man.

"I feel he needs to stay at Everton because there are things he needs to work on in his game. I'd like to see him more commanding from crosses and set pieces."
