With the transfer window looming in January, many managers will be looking at players who they feel can enhance their squad. Fans wait with baited breath not only in anticipation for who their team will sign, but also who they will sell. One thing the club do not want to get caught up in is a high profile controversial transfer. These are the moves that become the most talked about subjects in football and live long in the memory. With such huge amounts of money changing hands, each one has to be assessed again and again to make sure the buying club are sure that the player they're after is the right one for them. Sometimes however, there are some that cause such a stir that you wonder why they ever bothered looking the player up in the first place. Football fans are often called extremely fickle, but to my mind, the players are shown as the ones who are the most volatile. A player can sign for a club and decide within months, sometimes even weeks, that they made the wrong choice and start looking elsewhere. With so much at stake, making the wrong decision could be costly, and over the years there have been some deals that have been received with spectacular egregiousness. They have caused such a stink that some were even left fearing for their lives let alone their jobs. Transfers that felt right in the footballing sense but in every other way was just plain wrong. To give you some idea, here are the top five most controversial ones of all time.
