We created a number of chances in the first half at Villa Park - Michael Dawson headed the best against the post - but failed to capitalise.
The game changed with 20 minutes remaining when Calum Davenport was judged to have fouled Gabriel Agbonlahor in the penalty and was sent off. Juan Pablo Angel missed the penalty but we were left with 10 men and, with Dawson already off after taking another bang on the head, no recognised central defenders.
Luck then turned our way as Angel headed Jermain Defoe's corner into his own net to hand us a 1-0 lead.
Gareth Barry curled home a fine equaliser with 10 minutes to go and it was backs to the wall stuff after that with Pascal Chimbonda and Didier Zokora excelling as central defenders and Paul Robinson producing the save of the match to deny Angel.
Martin said: "It was a good first half performance, I thought we controlled it but we should have scored, we didn't and that gives you an awkward feeling again.
"Ghaly and Dawson had great chances, Defoe and Berbatov half-chances and I can remember coming to Villa Park and not creating as many opportunities.
"When we had everyone on the field we did well but the second half was totally different.
"We had to re-organise twice, Villa put us under pressure and we could have lost it in the end. Having said that, we could have nicked it as well and when you look at the game overall we deserved at least a point."
Martin Jol insisted that we deserved at least a point after Saturday's 1-1 draw against Aston Villa in the Premiership.
