Spanish attacker Michu has not been included in the Swansea City side that will take on Arsenal in the FA Cup at the Liberty Stadium this afternoon.

His absence is one of four changes made by manager Michael Laudrup, who has also handed starts to former Arsenal defender Kyle Bartley, Dwight Tiendalli, Nathan Dyer and Ki Sung-Yueng.

Meanwhile, German defender Per Mertesacker has been brought into the Arsenal starting lineup at the expense of Thomas Vermaelen.

Elsewhere, Theo Walcott will revert to a wider role, with Olivier Giroud likely to feature as a lone striker.

Swansea: Vorm; Tiendalli, Chico, Bartley, Davies; Britton, De Guzman, Ki, Routledge, Dyer; Graham

Arsenal: Szczesny; Sagna, Mertesacker, Koscielny, Gibbs; Arteta, Wilshere, Ramsey, Walcott, Cazorla; Giroud
