Millwall boss Neil Harris thought his side did enough to win Saturday's 1-1 Sky Bet Championship draw with Sunderland at The Den, but also bemoaned "the final movement" in the stalemate.
Bryan Oviedo's long-range effort gave The Black Cats the lead just before half-time, but Shaun Hutchinson poked home into the second-half to ensure a share of the spoils.
Harris stated that Sunderland had showed The Lions "respect" and also praised the team's response to going a goal down.
"I think it's a brilliant reality check for everyone associated with this football club," he said. "We played against Sunderland at home - who might be bottom of the League and had some struggles - but they've come and defended deep and given us respect here at The Den. They made it difficult for us to break them down.
"In the first-half, there was one team in it for 20-25 minutes, but then they grew into the game and scored a really good goal - however, the lead-up to it was a shambles from us. I'm not pleased about that, but the response after half-time was excellent.
"I think they had one entry into our penalty area, but we couldn't find that elusive second goal. The reality of it is that we've drawn against Sunderland at The Den and everybody is a little flat and disappointed."
The manager also stated that only one side would have gone on to win the three points.
"We put some really good balls in the box but didn't do enough to get on the end of them. We perhaps rushed things a little bit and needed to be a bit more composed. We also got into some really good positions, but perhaps it wasn't the final ball, it was the final movement.
"I can't fault the players' desire and effort to win the game, but we were perhaps lacklustre at times. We lacked a bit of the brilliance we've had in February, but we still did enough to win the game. There was only going to be one team that would go on to win the game - that was us."
