Carl Jenkinson will almost certainly deputise.
Santi Cazorla (remember him?) is still nowhere near fit - and we're still missing Theo Walcott, Alex Oxlade-Chamberlain and Lukas Podolski.
The lads will be looking to continue their winning run, but the Baggies won't make it easy for them. They're strong at home and can play a bit of football too - should be a good contest.
