Well, that didn't last long.
After stealing the top spot in the Premier League table from Arsenal in Week 23, the Citizens gave that throne right back to the Gunners with a 1-0 loss to Chelsea on Monday, Feb. 3.
Combine that with Arsenal's 2-0 win over Crystal Palace earlier in the week, and the Gunners are back on top.
Chelsea's win over the Citizens gives them a double over Manchester City for the league year. Still, it was hard to see this one coming considering it was at Etihad.
Entering Monday's match, Manchester City had gone 11-0-0 at Etihad this league year, and they had outscored opponents 42-9 while doing so.
No matter for the Blues, they blanked mighty Manchester City and a goal from Branislav Ivanovic in the 32nd minute was all that Jose Mourinho and company needed to pick up three points.
Chelsea and Manchester City both are two points back of Arsenal with 53 points.
Can you say upsets?
Sunderland went into St James' Park and thoroughly dismantled the Magpies, winning 3-0 behind goals from Fabio Borini, Adam Johnson and Jack Colback. It's fairly safe to say that Yohan Cabaye's presence was very, very missed by Newcastle, and the club's supporters will be annoyed that he wasn't properly replaced during the transfer window.
Frankly, they were annoyed during the match, as several fans ran onto the pitch and a bit of trash found its way down to the playing surface.
Of course, one team that did make a major splash, Manchester United, managed to still find a way to lose against Stoke City, 2-1.
While new man Juan Mata assisted on Robin van Persie's goal, the loss of two centre-forwards to injury, Jonny Evans and Phil Jones, doomed United. With Nemanja Vidic suspended and Rio Ferdinand left off the squad, United was vulnerable in the back and Stoke exploited that advantage.
Tottenham also potentially cost themselves points in the chase to finish in the top four, drawing with West Ham, 1-1, and falling a point behind Everton after the Toffees got past Aston Villa, 2-1.
Meanwhile, Cardiff City and Fulham remained 19th and 20th on the table, respectively, with the former losing to Norwich City, 2-1, and the latter getting smoked by Southampton, 3-0.
With Tottenham and Manchester United faltering, the top four of City, Arsenal, Chelsea and Liverpool have the opportunity to distance themselves further from the field, while Everon kept themselves in striking distance.
Even with Mata, it's becoming hard to envision United qualifying for the Champions League next season. With a Liverpool win, the Red Devils will be a shocking nine points out of fourth place.
