WEST Ham manager Gianfranco Zola must decide whether to change a winning side in the Barclays Premier League match at Arsenal tomorrow.

Carlton Cole and David Di Michele were both on target in the 2-0 win over Hull on Wednesday, but new signing Savio Nsereko could be brought into the starting XI after coming off the bench in midweek.

Midfielder Kieron Dyer - who had been out with a broken leg - will continue to have further checks on a muscle injury and misses out. Striker Dean Ashton (ankle) and defender Danny Gabbidon (groin) are long-term absentees.

Provisional squad: Green, Neill, Collins, Upson, Ilunga, Behrami, Parker, Collison, Noble, Di Michele, Cole, Lastuvka, Nsereko, Tristan, Tomkins, Sears, Faubert, Boa Morte.
