Dean Smith has been surprised by the signings Wolves has made, believing that record signing Ruben Neves would have moved to the Premier League.
The Black Country side have spent heavily during the transfer window, with Neves joining for a fee of £15million, and are seen as one of the sides capable of winning promotion.
Wolves have made a strong start to the league campaign, winning three and losing one of their four games, and Smith knows his side have a tough task facing them.
“The standard of players they've got has surprised me. Neves I thought would have gone to the Premier League. It shows they've got some pulling power there,” the Brentford head coach said.
“They've started the season really well. They've signed some really good players and spent a lot of money. Neves and Diogo Jota coming in; they've got some really good players in their ranks. They'll be a different team to last year but they'll be a tough game for us.”
Nuno Santo has been consistent with his selection, not making any changes in the league, and Smith is focused on what his side can do against them, not how Wolves will line up.
He added: “We have to concentrate on ourselves and what we do. The fact they've not changed the team once tells you how they might go against us.
“The manager hasn't been prone to changing the team too much. It's about concentrating on us and what we do.”
Smith, on the other hand, has been making regular changes to his side and he faces a further selection headache after the 4-1 win at west London rivals QPR.
He explained: “I want them to go and put in performances that gives me a problem for picking teams.
“I don't think anybody played really badly against Ipswich and, after they scored the second goal, we rarely tested the keeper.
“The players came in on Tuesday and upped the tempo and our attacking play was better. It gives me selection problems going into the game.”
