Aston Villa boss Dean Smith admits he's been impressed by new West Ham striker Sebastien Haller.

Villa will host West Ham on Monday night.

"They are certainly a threat going forward," said Smith. "I watched their game against Watford the other day and it was end to end - it could have been 5-5.

"If you look at the expected-goals table they'll be at the top for entertainment. I think they can score a lot but concede a lot as well - I'm guessing I know what they'll have been working on during the international period.

"In signing Haller up front he looks a really good centre forward. They paid a lot of money for him but he's got a couple of good goals already and looks a handful."

He added: "There's going to be people who will put comparisons but we've told Wes just concentrate on his own game. Concentrate on what he's doing and go and get another performance like he did against Everton.

"They've got a lot of similarities. When I watched a lot of Wes, he created a lot of goals as well as scored them. That was a big part of his game that I liked and attracted me to him. I think that's probably one of the biggest differences."
