West Brom midfielder James Morrison believes Aston Villa cannot be underestimated despite the contrasting fortunes of the clubs going into Saturday's derby.
The Baggies are riding high in ninth in the Barclays Premier League after winning their last two matches, scoring seven goals into the bargain.
Villa, meanwhile, are just two points above the relegation zone on the back of a run of three successive league defeats.
Ahead of the game at Villa Park, Morrison rightly concedes that "form goes out of the window in a derby".
Speaking to the Birmingham Mail he added: "We're on a decent run and they haven't been at their best, but they've got some decent players and we'll have to be wary of them.
"They'll be looking to bounce back after defeats. It'll be a tough game. But we're on a high, so it will be interesting."
