Chelsea have made contact with West Ham with the intent of signing Andy Carroll on a permanent deal, but the Hammers will not sell him for less than his valuation, Sky Sports News understands. The East London club's stance could change if Blues striker Michy Batshuayi was included as part of a deal for Carroll, but Spanish club Sevilla are growing increasingly confident of signing the Belgian. Chelsea are coming to life towards the end of the transfer window, with the club understood to have made known their interest in signing Alexis Sanchez out from under the noses of Manchester United and Manchester City.
