"We've got a group of players in there who are up for the challenge and this is a team that I think will play in the Premier League.
"It was difficult to take being 1-0 down at half-time, but it was a terrific response from our players after the break.
"I played with one up front because they are a top side and I thought the guys who came on changed the game."
As for Ngog, the Scot was happy with his overall contribution despite the red card
"Strikers have got to live on the edge and he got his goal and got sent off and I was happy with that," he said.
"Unfortunately, he just boiled over the top, but I've no complaints with him because he was fantastic."
Tempers flared in the dying minutes after Ngog was sent off and Mark Hudson had a penalty claim turned down by the referee.
The result ended a run of three straight wins for the Bluebirds, who are now only top of the table on goal difference.
Cardiff boss Malky Mackay was left furious with the officials' performances and also believed that the home side's penalty was a soft one.
"Do I feel hard done by? In a word yes," said Mackay.
"Bolton had to come out and have a go in the second half and they got a penalty from nothing
"David Ngog dived before he was even touched so if he gives that he has to give us a penalty with Hudson.
"I certainly hope the referee and the linesman look at their performances because neither of them were good enough tonight.
"They had a goal which could have been given but the standard of officiating overall was not good enough.
"It has ultimately cost us the game and that could prove to be vital at the end of the season."
