Saturday will play host to one of the biggest Manchester derbies in Premier League history.
Manchester United and Manchester City are both firm favourites to win the title this season following a summer where they spent £174 million and £150 million respectively - an eye-watering total of £324 million.
Incredibly, the two Manchester clubs contributed almost a third of the Premier League's total spend in the transfer window, which exceeded £1 billion for the first time.

Money aside, it's the fact Jose Mourinho and Pep Guardiola will face each other for the first time since their management days in La Liga.
Their long-standing feud is what makes their reunion such a spectacle.

Reporters have asked the pair to comment on one another in the build-up but, sensibly, they've both resisted the urge to criticise and instead played it safe.
In July, Mourinho gave a frustrated response to questions about whether he will shake Guardiola's hand when they meet.
"To qualify the question I would use some impolite words," the Portuguese said.
"Of course I'll shake his hand. I don't understand the question to Guardiola and I don't understand the question to myself.
"We worked together at Barcelona and we worked against each other in Spain. I don't see the reason for the question."
And two weeks earlier, Guardiola revealed how Mourinho has made him a better manager.
He said: "It's not about him or me. It's doesn't matter about the team, it's so difficult to win here.
"We played many times against each other and the big coaches like Jose, they helped me reach another level as a coach."
There remains a rift between the former Barcelona and Real Madrid managers and so, Mourinho has reportedly hatched a plan to make peace.
According to The Sun, he has invited - or will invite - Guardiola for a drink in his recently-revamped office following the Manchester derby.
Whereas Mourinho is accustomed to drinking a glass of wine with managers after Premier League games, his Spanish counterpart is completely unbeknown to the tradition.
Whether Guardiola accepts the offer - although you'd like to think he would - remains to be seen, but much could depend on the outcome of the clash.
Either way, all signs point towards a thrilling and memorable affair.
