The ninth-placed Bees remain in contention for European football and, depending on results elsewhere, could clinch a qualification spot with a win or draw in this game.
When asked how he intends to set up his side, Andrews responded: “It’s a little bit about our players and where they’re at – physically, form, opposition. We’re willing to be a little bit unpredictable with how we attack at times.
“On Sunday (against Crystal Palace) we played Dango (Ouattara) a little bit more narrow, closer to (Igor) Thiago.
“We didn’t start Kevin (Damage) last weekend, so we wanted those two to come closer as a pair. We wanted to get Dams (Mikkel Damsgaard) and Mathi (Jensen) a little bit closer on occasions.
“There’s always a little bit of method in the madness, I suppose.”
