Former England goalkeeper David Seaman believes Chelsea are facing a huge blow ahead of Sunday's crunch clash with Arsenal by not having Kepa Arrizabalaga available.
Spanish stopper Kepa has been in fine form for the Blues since Graham Potter took over - he started the first 10 games under the Englishman before limping of with a foot injury at half-time in last weekend's dismal 4-1 defeat to Brighton.
It has been a remarkable turnaround for the keeper, who's stock had dropped so low under Potter's predecessor Thomas Tuchel after struggling for form that he was expected to depart in the summer.
