26/08/2011 09:17 +0100 – Juan Mata is unlikely to start Chelsea but the Spain winger, who completed his move from Valencia on Wednesday, could be on the bench at Stamford Bridge. Fellow new boy Oriol Romeu is in contention to start, but the game comes slightly too soon for David Luiz (thigh), while Petr Cech and Michael Essien (both knee) remain sidelined and Daniel Sturridge serves the final instalment of his three-match ban. Norwich will be without defender Daniel Ayala, who is set to miss up to eight weeks with a knee injury. Playmaker Wes Hoolahan (hamstring) will be monitored, centre-back Leon Barnett returns after a one-match ban, as manager Paul Lambert is set to make changes from the side thrashed 4-0 at home in the Carling Cup on Tuesday night. Striker James Vaughan and centre-half Elliott Ward are still sidelined after picking up minor knee injuries during pre-season. Chelsea (from): Hilario, Ivanovic, Bosingwa, Ferreira, Terry, Alex, Cole, Mikel, Romeu, McEachran, Lampard, Ramires, Benayoun, Mata, Malouda, Torres, Drogba, Anelka, Kalou, Lukaku, Turnbull. Norwich (from): Ruddy, Tierney, Barnett, de Laet, Naughton, Bennett, Johnson, Fox, Crofts, Pilkington, Holt, Rudd, Martin, Whitbread, Hoolahan, Surman, Jackson, Morison.
