With no win in three games, it's fair to say that Manchester City are enduring something of a mini-slump. After throwing away a two goal lead at CSKA Moscow to draw 2-2, Manuel Pellegrini's side went on to lose 2-1 at West Ham United before crashing out of the Capital One Cup following a 2-0 defeat to Newcastle United.
City have the perfect chance to bounce back this weekend though, as they renew their rivalry with cross-city rivals Manchester United at the Etihad Stadium, looking to carry on their recent success against the red half of Manchester.
However, with David Silva ruled out injured and Fernandinho dreadfully out of form, the problems are mounting for Pellegrini - and summer signing Eliaquim Mangala can be added to that ever growing list.
The French international, 23, joined City for £32m from Porto this summer, and arrived with a huge reputation after playing a starring role in Portugal.
Chelsea and Manchester United had also been linked with Mangala, but City tied up that huge deal this summer, with the intention of pairing him with Vincent Kompany in the long-term.
However, Mangala has been pressed into first team action early on, and so far, it's been a disaster. West Ham's Enner Valencia ran rings around Mangala last weekend, and he looks generally off the pace, too rash and positionally naive.
Yet there are fans already calling him the worst signing in recent Premier League history, and that's just outrageous at this stage.
Mangala has only just arrived in England, and he was a project to begin with. City have bought into Mangala's physical traits in a bid to mould him - possibly into the next Kompany - and in doing so, there are going to be ups and downs.
Given time and patience, Mangala can still be the defender City have been looking for - and fans have to take the rough with the smooth for the time being.
