David Moyes' side are only two places above Wolves in the table, but manager Julen Lopetegui was full of praise for the West Ham boss.
"I've known David for a long time," Lopetegui said.
"He was a coach in San Sebastian [Real Sociedad] and they are my team. They are from my country and my part of Spain, and after we have had a very good relationship.
"When I was the national team coach, we spoke a lot, and then last year, we played against West Ham with Sevilla. He has done a fantastic job in England and with West Ham, he has a very good squad, with very good players and we have to be ready.
"The most important thing is to be able to start and do a very good match against a very good team."
Wolves have played in two cup games across the last seven days, drawing 1-1 with Liverpool in the FA Cup before losing 4-3 on penalties against Nottingham Forest in the Carabao Cup.
The Forest loss means Lopetegui's side missed the chance to reach the semi-finals of the competition, but he is determined to shift attention to performances in the league.
