The Leeds defender wasn't happy with his contribution, despite many feeling Sheffield Wednesday had scored a superb goal.
Indeed, Wednesday took the lead at Elland Road with a fabulous strike from Matias. But Bamba believes the overall goal was 'sloppy.'
The 30-year-old wasn't critical of Matias's role in rifling the ball into the back of the net but says Leeds - himself included, should have defended better.
And the centre-back also feels Leeds should have beaten Sheffield Wednesday over the course of the 90 minutes.
He told BBC Radio Leeds: "We conceded a sloppy goal, to be honest. We should have done better and got three points at home.
"The finish is great but we should have done better at the start. I thought it was off, I spoke to the ref. But I looked after and it wasn't, I should have stayed with the man, to be honest."
Remarkably, Leeds have now drawn four out of four Championship games. But so frequent has a draw become for Uwe Rosler's men, there isn't really anything remarkable about it at all.
The encouraging aspect for United on this occasion was that it wasn't them giving up a lead. After Sheffield Wednesday's sloppy... wondergoal, Leeds hit back and took the game to the visitors.
Just like last season, there was no eventual winner of this Yorkshire derby - and Leeds are still waiting for their first competitive win under Rosler after the 1-1 stalemate.
