I like your logic there AA.
Walcott probably is a good choice, if he's still our player on the day. This is likely to be much more end to end than either of our first two encounters so he should have a bit more space to run into.
AOC, Podolski, Giroud, Walcott though - so much uncertainty in what those four would produce.
Not sure on what our ideal central defensive partnership is. I think the tall/medium partnership theory isn't quite what it's cracked up to be.
