The Republic of Ireland star has been emerged as one of the very best right-sided defenders in the Premier League under Roberto Martinez at Goodison Park, with his attacking instincts having been fully utilised by the Spaniard.
His displays have attracted the likes of Manchester United in the past, and now it has emerged that Jose Mourinho is keen to lure him to Stamford Bridge.
Everton are, naturally, reluctant to sell their 26-year-old ace, but the Blues are hopeful that he can be lured to London by the virtual guarantee of Champions League action and regular shots at major silverware.
Branislav Ivanovic is Mourinho’s current right-back of choice, but Coleman could offer a different set of skills down the flank than the solid Serbian.
Any deal will mark a massive profit for Everton, who bought the full-back from Sligo Rovers for just £60,000 back in 2009.
The Merseysiders are watching Barcelona’s Martin Montoya and Rhys Bennett of Rochdale as they line up potential replacements.
