Tony Pulis has made four changes for this evening's crucial Coca-Cola Championship clash against Bristol City.

Liam Lawrence, Glenn Whelan, Ryan Shawcross and Mamady Sidibe all return to the starting line up as the City boss aims to guide the Potters into the automatic promotion places.

On loan Derby man Stephen Pearson drops to the bench with 15 goal midfielder Lawrence returning after overcoming a groin injury.

Shola Ameobi declared himself fit ahead of the game but Pulis opts to start Sidibe in attack partnering Ricardo Fuller.

Glenn Whelan also returns to the heart of midfield at the expense of Danny Pugh, who is also named on the bench.

In defence Andy Griffin's hamstring injury means a return for Shawcross, who impressed immensely during last weekends 2-1 win at Coventry City.

Stoke City (4-4-2): Nash; Riggott, Cort, Shawcross, Dickinson; Lawrence, Delap (C), Whelan, Cresswell; Sidibe, Fuller. Subs: Simonsen, Wilkinson, Pugh, Pearson, Ameobi.

Bristol City (4-4-2): Basso; Orr, McCombe, Carey (C), McAllister; Wilson, Elliott, Skuse, McIndoe; Byfield, Adebola. Subs: Weale, Fontaine, Noble, Vasko, Trundle.
