Demba Ba v Ryan Shawcross
With Fernando Torres injured, Samuel Eto’o has earned the status of first choice Chelsea striker, with Demba Ba therefore likely to start in the FA Cup.
The Senegal international has been underwhelming thus far for the Blues after an immensely prolific spell at Newcastle United, but puts in a great deal of effort, and Stoke captain Ryan Shawcross will be wary he may be moved across the pitch.
Few players mark more tightly than Shawcross though, and Ba may find it difficult to find space to exploit.
