Paul Merson has told Sky Sports' Soccer Saturday that Aston Villa made a big mistake by not replacing Christian Benteke in the summer transfer window.
Villa sold Benteke to Liverpool for a fee which the Guardian valued at £32.5 million, and they went to the Championship to replace him by signing Rudy Gestede from Blackburn Rovers.
Merson feels that this was a mistake and, although he believes Gestede is a good player, the former Arsenal midfielder claims they should have gone for someone of a higher calibre.
"If you sell someone for £30 million like Benteke, you have to bring in someone who is worth at least £12-15 million," he said.
"Gestede is a good player, and he's done well, but you cannot go for a Championship player to take Benteke's place."
Villa have missed Benteke desperately so far this season, with the side not looking particularly threatening going forward.
Although Gestede has shown glimpses of quality, he doesn't possess the same goal threat as Benteke did during his time at Villa Park.
Gestede has scored four times in his opening 10 appearances for the Claret and Blues, but he has some way to go if he is to match Benteke's return of 16 from last term.
Villa's failure to find a replacement for Benteke has left them in big trouble, and the side are currently four points adrift of safety in the Premier League standings.
