LAWRO'S PREDICTION
Crystal Palace got a bit of a hammering at the hands of Tottenham last weekend but they are still perfectly safe from relegation.
West Brom are obviously in much deeper trouble. They have picked up a few points in recent weeks by keeping things tight, and I am sure that will be their plan here too - but Wilfried Zaha is back for Palace and he could make the difference.
