The City supporters made their point by booing on the final whistle but Coleman seemed unconcerned saying to the club website: "I don't think it was a bad point but we maybe could have won it.
"Having said that it's a clean sheet, it stops a run of two straight defeats in the league and I'm quite happy to take a point.
"We lost to Doncaster in the worst possible fashion, we've had two weeks to think about that and whereas there were no positives at Doncaster, there were plenty of positives for me to take from this game.
"Preston have been fantastic in their first four games, they were unbeaten going into this match and I think we saw in glimpses today what a good side they are.
"We had enough chances to win the game and on another day, with the attackers we had out on the pitch I think we would have scored goals, but it just wasn't to be today. If we'd have won today it would have been a great result but it's a point and that's a step forward.
"Isaac did very well in his first 90 minutes since the end of last season. He's a midfielder naturally but he slots in at right-back and gives you everything. Unfortunately the De La Cruz deal looks dead but if Isaac can give us that at right-back I will be happy.
"Doyler did well too. We rested Aron after he's been away on international duty and I thought Michael did very well in the middle."
