Manchester City have garnered a reputation for being astute in the transfer market since they were purchased by Sheikh Mansour back in 2008.
City have gone on to dominate domestically, and the club have certainly not been shy to splash the cash during Mansour's time at the helm. But even though the Premier League champions have an impressive track record in the market, they have already proven that they are not immune from mishaps.
And in truth, it's hard to think of a more uninspiring signing in recent top-flight history than Eliaquim Mangala: the centre-half Manchester City acquired from FC Porto for £42million back in 2014.
