Bradford v Villa: Weimann backed to repeat cup heroics
Weimann was Villa's match-winner in the quarter-final victory over Norwich and will be hoping for a repeat in tonight's last four clash at Bradford.
The 21-year-old took his goal tally for the season to seven with a crucial winner against Ipswich in the FA Cup at the weekend.
Lambert admits Weimann's performances have slipped under the radar at times because of striker partner Christian Benteke's explosion on to the top-flight scene.
"He has scored some very important goals and he's playing really well," said the Villa boss.
"He's only young, only 21, and what you get from him is he's really confident at the minute and has great enthusiasm for the game.
"Because of the performances of Christian, he's tended to get a bit overlooked.
"But I know the value he's got and the value of what he's done for the team."
Lambert says Weimann is always prepared to play through the pain barrier for his team.
"Even if he's not been fully fit, he's been willing to stand up and say he's willing to play, which is a great thing," he added.
"I can't speak highly enough of him as a guy and as a footballer."
Make sure you're there to back the lads against Southampton.
