Paul Lambert praised a 'fantastic' second-half performance after a triple substitution helped Aston Villa to secure a 2-2 draw at West Bromwich Albion.
Shane Long scored twice inside the opening 11 minutes to put West Brom in control at The Hawthorns before Lambert threw on the fit-again Fabian Delph, Andreas Weimann and Gabriel Agbonlahor on 57 minutes.
Weimann almost scored immediately before goals from Karim El Ahmadi and Ashley Westwood earned Villa a point in the West Midlands derby.
Villa boss Lambert told Sky Sports: "I thought second half we were fantastic, terrific and were really resolute.
"We were down 2-0 in 10 minutes and we were thinking that we need to hang in to half-time and get them back in. But second half we were outstanding.
"I don't think anybody can label our team as having a lack of character and to come back in a derby game, especially here with the atmosphere, and to do it in the way they've done it, I've nothing but praise for them."
Lambert also considered making changes at half-time, saying: "We spoke about it and we thought we had to get them on pretty quickly, but we were actually going to wait a bit longer.
"But we thought we needed to get a goal and the three of them made a huge contribution. They have been big players those three and to lose them at the time we did was a bit of blow.
"Full credit to the three of them. They only started to train on Friday, they came on and I thought they were outstanding."
The result keeps Villa in 12th position in the Premier League and Lambert is happy with the progress which is being made at the club.
He continued: "We've just got to keep growing the football club. We've only been here 15, 16 months and we had to strip it right back as everybody knows.
"People were criticising us for doing certain things, but we have strong beliefs and stuck with it, and hopefully now people are starting to see we've got a really good side.
"They've got great energy, but they'll grow and, if we can keep them for a few years longer, and keep the club growing, then we'll do alright."
