MATCH PREVIEW
Just when Manchester City thought that they had the monopoly on big-money signings in this transfer window, Aston Villa took one look at their own lowly league placing and realised it was time to throw caution to the wind and splurge an astonishing £30m on Darren Bent and Jean Makoun.
They are having problems, but Darren Bent has a record close to one goal every two games and he will make a big difference and I think this will make our task on Saturday even harder
Man City boss Roberto Mancini
January is traditionally a month for financial prudence, and given that Villa had signed only one player in the previous two transfer windows combined, the shock decision by owner Randy Lerner to loosen the purse strings speaks volumes for the perilous position that the club finds itself in.
They are currently only out of the bottom three on goal difference, and desperately need Bent's goals to propel them away from a potential relegation battle that would have seemed unthinkable at the start of the season.
Bent's first task is to try and breach a City defence that has suddenly gone from impregnable to porous. After keeping three successive clean sheets in the league, they have conceded five goals in their two games against Wolves and Leicester - much to the annoyance of manager Roberto Mancini.
It is a problem that Villa boss Gerard Houllier is all too familiar with as his side have conceded a whopping 39 goals this season. City brutally exposed their defensive fragility when the sides clashed over the festive period, with Mario Balotelli helping himself to an easy hat-trick in a 4-0 thrashing.
