Coming into the summer there was one position where it was clear Arsenal needed to strengthen. The Gunners had just missed out on Champions League qualification in after a closely fought race with Tottenham. What had seen their local rivals pip them to the post was arguably a superior goal threat with Spurs managing eight more goals in the league.
As a result it was clear they needed a new centre forward to provide the point to the attack that Arsenal were so clearly lacking. Plenty of candidates were considered, but Mikel Arteta and Edu ultimately opted for a reunion with Gabriel Jesus.
So far it's safe to say the deal has worked out pretty well for everyone involve. Arsenal's front line has been almost entirely transformed from the immobility and impotency that defined it last season to the second-highest scoring team in the Premier League. In another world though, things could have gone very differently.
