Shay Given believes Manchester City have the capability to go unbeaten for the rest of the season to mount a significant title challenge.
City trail Arsenal by six points but Sunday's win at Liverpool has prompted discussion over their credentials.
"There are still fragilities we haven't seen in the past perhaps," ex-City keeper Given told BBC Sounds' Monday Night Club.
"But they still have the armoury I think to go on a crazy run now and be unbeaten and all that stuff."
Chris Sutton and journalist Rory Smith said they doubted this City team can go on the kind of unbeaten run that previous Pep Guardiola sides have delivered to close out title races.
But Given insisted on his claim, adding: "It's not that big of a statement to say that.
"The manner in which they won on Sunday, the psychological side. They have gone 'this is ours for the taking'. The belief runs through the whole club and fans where they think, 'do you know what, we still have a great chance'.
"That will give them belief for this run-in.
"The defence was conceding too many goals but I'd like to think they have sewed up a bit. Rodri we don't think is up to full speed yet but it feels like as every week goes by he's getting a bit better, fitter and reading the game better. There are a lot of things coming together for City – Guehi, the calmness he brings at the back."
