Steve Clarke was left feeling disappointed after West Bromwich Albion blew a two-goal lead to draw 2-2 at home with Aston Villa.
Republic of Ireland striker Shane Long scored twice inside the opening 11 minutes to put West Brom in control before Karim El Ahmadi and Ashley Westwood replied in the second half for Villa.
Stephane Sessegnon fluffed a fine chance to score a third goal for West Brom in the first half and Clarke lamented a sixth draw in 12 Premier League games this season.
"I think when you're leading comfortably 2-0 midway through the second half, you feel you should go on and get three points," Clarke told Sky Sports.
"Villa made a few changes and the energy of the substitutes seemed to unsettle us a little bit. We gave away a bad goal and that gave Villa a bit of momentum in the game, and they took advantage of it.
"I think we missed one clear-cut chance to make it 3-0, and if it goes 3-0 at that stage, it's probably over, although in a local derby you never know.
"We knew at half-time that the next goal was going to be crucial.
"We had a similar situation last year in the game when we were the team chasing the game, and sometimes when you're chasing the game from 2-0 down, you take risks and you get a little bit of luck, and Villa fought hard for their luck.
"At the moment, the feeling is more disappointment than anything else. I felt it was a game we could get three points from.
"I've touched on it a couple of times this season that I feel we're drawing too many games, and we have to turn those draws into wins.
"But there are some positives, especially from the first half where we controlled the game."
The West Brom boss also praised the contribution of Long, who had been close to leaving the club before the close of the summer transfer window.
Clarke added: "Shane has been working hard for that type of performance. He's in a good moment.
"Shane has been on a good run of form and hopefully he can keep it going."
