WBA is an interesting team - I can't remember the last time I saw a team so completely built on physique and experience. Against Swansea yesterday - their youngest player starting was Matt Phillips who is 25.
In defense, Brunt 32, Olsson 33, McAuley 37 and Nyom 28. Midfield Phillips 26, Fletcher 32, Yacob 29, Morrison 30 and Chadli 27 and up front Rondon who is 27.
So in my opinion - we should keep the ball and whatever we do, don't drop down and let them start crossing the ball. They lack pace so I would rather we push them back and risk the occational counter.
In fact, we should play exactly like we did against Palace in the first half - just with a bit more urgency.
