Andy Awford believes Pompey warranted a victory rather than a 1-1 draw after a dominant second-half.
The Blues were trailing 1-0 to Cheltenham at half-time following Omari Sterling-James’ 42nd minute strike.
Yet they raised their intensity from the off of the second period and levelled through Nigel Atangana’s first for the club in the 56th minute.
Pompey continued to boss possession yet the match winner against the Robins eluded them.
But Awford was delighted with the display which ended five successive away defeats.
He said: ‘It is all about results, obviously, but I think the manner of the performance was excellent, we came with a game plan and the players carried it out.
‘We were unfortunate to be behind at half-time, it was the only shot on target I can remember them having in the first-half and the lads showed plenty of character and dug in.
‘We fully deserved a point and probably deserved to win the game on possession and chances created.
‘I have to say the supporters were absolutely magnificent today again, that is why I took all the players up to them at the end, I thought it was important we went as a group and showed them we are all in it together and we have to stick together.
‘The way they spurred us on in the second half was fantastic.’
