Dewi Morris told Sky Sports HD that Gloucester's weekend win at Northampton proves they are good enough to make the Premiership play-offs.
The Cherry and Whites' 27-11 victory at Franklin's Gardens - revenge for an LV= Cup defeat at the hands of Saints a fortnight ago - propelled them above Jim Mallinder's charges in the table and up to fifth.
Gloucester had been conquered in their previous two Premiership clashes - at home to London Irish and away to Leicester - but Morris reckons the Kingsholm side showed enough, both offensively and defensively, against Northampton to suggest they will be in the top-four shake-up.
"(Head coach) Nigel Davies and all the Gloucester coaches can hold their heads up high," said the Rugby Club regular. "They were confident their team could do a job and, to a man, they did.
"Robert Cook had his kicking boots on at the back and Jonny May, who has incredible pace, scored two tries, and as a cohesive unit Gloucester seemed to know exactly how to beat Northampton.
"That's the sign of a good side and proves they have genuine top-four aspirations.
"Gloucester were sensational today but Mike Tindall, who will tackle proverbial horses week in, week out, and Tim Molenaar stepped up and made the big tackles at centre.
"They dealt with wave after wave; when Northampton said: 'We're getting back into it' those two said: 'No, you're not'."
Northampton flanker Calum Clark, currently sidelined with a shoulder injury, watched the action with Morris in the Sky Sports studio - and was less than enamoured with what he saw from his team as they suffered their third Premiership home defeat of the campaign.
"Gloucester took their chances but it was a very bad performance from us - and we need a reaction," said the 23-year-old, who signed for Saints from Leeds in 2010.
"We have done it before but it's not good enough to do it for one week and then take your foot off the gas. We need to work out what's going wrong and come back next week and build momentum."
Morris added: "Saints can beat anyone so they can get up there (in the play-off) hunt, but they have to be consistent and cut out the poor discipline and the giving away of penalties."
