Birmingham boss Steve Bruce has again hit out at owner David Sullivan for his criticism of the 7-0 loss to Liverpool.
Bruce was unhappy at Sullivan for airing his views in public after the FA Cup collapse.
And after the 3-0 defeat at Manchester United, Bruce added: "Maybe there is method in his madness but I did not like my owner's comments.
"Where I come from, in situations like that, you batten down the hatches, say nothing and come out fighting."
He added: "Everyone is entitled to their opinion but I did not agree with his comments."
Bruce came under further pressure following the heavy defeat at Old Trafford.
But the former Manchester United skipper believes the supporters are still behind him - despite their position in the relegation zone.
"The vast majority of the letters I have had from our fans have been urging me to stay on," he said.
Bruce admitted they are in a three-way battle with West Brom and Portsmouth to avoid the drop.
But he said he is more determined than ever to pull his side clear of the drop zone.
"I've a great affinity with the club," said Bruce, referring to the 10 years he had at Old Trafford as a player.
"But I'm the Birmingham manager now and this performance has made me more resilient than ever to have a right good go at it (beating the drop).
"We rode our luck at times, but in the second half we gave it a go.
"Fair play to the players, they've been criticised from pillar to post since that defeat and we needed to respond.
"We were beaten fair and square against United, but the players showed plenty of passion for their shirts."
Manchester United boss Alex Ferguson, meanwhile, admitted he did not enjoy seeing his former skipper in such a perilous position.
Their win over Blues followed a recent victory over relegation-threatened West Brom - managed by another of Ferguson's former leaders, Bryan Robson.
Ferguson said: "It is agony. Steve and Bryan were great captains of our club in the early years when we were still striving to get there and I really feel for them.

"Their quality does not deserve them to be in the position they are in. But they will fight on because they are battlers."
Ferguson was pleased to see his side collect their seventh straight Premiership win but was disgruntled at their showing after the interval.
He said: "I was disappointed with the second half, especially after the first half which was in keeping with our recent performances.
"We were slack and slow to start off with after the break and that encouraged Birmingham on to us.
"It's frustrating to think that we've now got the consistency to our game that we lacked earlier in the campaign.
"But we had problems with injuries then and had to move players into different positions, but much of the change has come about because of the midfield getting settled."
