Arsenal fans will today be enjoying that warm fuzzy feeling you get when your team has gone away from home against the Premier League champions, one of their biggest rivals, and come away with three points after a terrific display.
It was a remarkable performance, their most composed in such a situation for many a year, and more good news could news could well be on the way after it was reported that talks had been taking place between the Gunners and a potential January signing.
"Arsenal cannot hope to compete with the spending power of the reigning Ligue 1 champions"
According to The Sun, representatives of Moussa Sissoko have been holding talks with Arsenal this smooth about a possible transfer, as Arsene Wenger looks to provide further cover for his midfield.
The Newcastle United star has been in very impressive form this season and has been linked with a possible switch to Emirates Stadium for some time. However, there were also reports claiming that Paris Saint-Germain were in advanced negotiations.
Arsenal cannot hope to compete with the spending power of the reigning Ligue 1 champions, but reports of a possible move to Parc des Princes have gone quiet and it feels as though that avenue is closed.
Wenger has had severe injury problems in his season, with several of his leading midfielders out for significant periods. It was made worse last week when Mikel Arteta was ruled out for the next three months, leaving him short of experience in defensive midfield.
Mesut Özil and Aasron Ramsey have recently returned from injuries to bolster options, while Jack Wilshere's return is expected next month, but players screening the midfield are at a shortage.
It is debatable whether Sissoko is actually suited to this role, as he has looked most impressive when marauding forward, but the 25-year-old would at least add some pace and power to the Gunners midfield - Wenger does not need another attacking midfielder.
Sissoko has become a key member of the Newcastle squad, but owner Mike Ashley has consistently shown a willingness to sell his most valuable assets. As Newcastle signed Sissoko for only £1.8million from Toulouse in 2013, there is a considerable profit to be made.
However, on Monday morning Wenger likely be asking himself if he actually needs to bring in another midfielder after the team's performance at Manchester City. Francis Coquelin was one of the top performers on the day, playing a screening role in midfield.
New Hero Emerges
When he was sent out on loan to Charlton Athletic earlier this season it looked certain his career with Arsenal would be over come the end of the season. But injuries meant an emergency recall was required and he has grasped his chance worth both hands.
Mathieu Flamini was not having the bet season as it was, but the emergence of his young compatriot as a viable option has seen the pecking order change. Coquelin's desire to break up attacks and disciplined protection of the defence has been admirable.
