The North London outfit are currently in sixth place in the Premier League table, but recorded an emphatic 5-1 win against Sunderland five days ago at White Hart Lane.
Sherwood told reporters prior to today's clash at The Hawthorns: "We are on the back of a good win and the boys are confident. West Brom got their first win for a long time and will be confident as well.
"Today we are lucky enough to be healthy and we will go with same team and play an attacking way.
"When we play against the top teams, it is a technical mismatch, they are better than us, that is not the case when we play the other teams."
