Arsenal have made three changes for tonight's FA Cup third-round replay against Swansea City at the Emirates Stadium.

Per Mertesacker has replaced Laurent Koscielny following the Frenchman's red card in Sunday's 1-1 draw with Manchester City.

Meanwhile, Francis Coquelin and Olivier Giroud have been named in place of Alex Oxlade-Chamberlain and Lukas Podolski.

Swansea boss Michael Laudrup has chosen to rest top scorer Michu as the visitors bring in four new faces.

Kyle Bartley, Jonathan de Guzman, Wayne Routledge and Danny Graham all start.
