Raul Jimenez has warned Wolves must be wary of Espanyol despite their struggles in La Liga.
The two clubs will meet in the Europa League Round of 32 last week.
"Of course I know it, many Mexican players have played there," said Jimenez.
"It's a team that's talked about a lot in Spain, and we know it's going to be a tough match.
"It's going to be hard, but they also have their own weaknesses and we can take advantage of them."
