It's the Manchester Derby this upcoming weekend and you can already place bets on the Premier League Betfair odds market. If you've been paying attention to the Betfair odds on the Premier League winners, you will see that Manchester City are currently favourites for the title. Considering that they are the only team yet to lose a game this season and are 8 points clear, this is no surprise. While City will want to extend their lead to 11 points with victory against their rivals, United will want to put City's winning streak to an end and place pressure on City by reducing the lead to only 5 points.

Under Guardiola and Mourinho, both City and United have spent large sums on money to build the squad they want. Whilst Guardiola has opted for more technical players for his possession-oriented playstyle, Mourinho has brought more physical players for his direct playstyle. Although they are vastly different style, combined they have spent over £600 million on players.

As you'll notice from this infographic, this spending by both teams has been occurring for the last decade. This has led to both teams having some of the most expensive teams assembled in world football.
