Blues join chase for United target.
Chelsea are reportedly keen on signing Everton right-back Seamus Coleman to become their long-term answer in that position, according to the Sun.
The Blues are planning to use current right-back Branislav Ivanovic in the centre, where he can also play, with Jose Mourinho a big fan of the in-form Coleman, who has shone in recent times at Goodison Park.
Valued at around £20m, the Republic of Ireland international could make a superb addition for the club as they look to strengthen their depth at the back.
However, Manchester United are also interested in the player and oculd provide strong competition for his signature.
