The Gunners followed up their 3-2 FA Cup final win over Hull City with the blockbuster signing of Barcelona forward Alexis Sanchez, with fans now hoping that the Chilean can lead them to more trophies having ended their nine-year drought.
Manager Arsene Wenger did also have to replace Bacary Sagna after his long-serving right back moved on to Manchester City, and Newcastle United's Mathieu Debuchy arrived for around £12m in his place. That appeared to be the end of the matter, but recent speculation has suggested that Wenger is in the market for another right back.
Despite already having Carl Jenkinson and Hector Bellerin in reserve, Wenger was strongly linked with a swoop to sign Atletico youngster Manquillo - only for Premier League rivals Liverpool to swoop in and take the lead in the race for his signature.
Manquillo, 20, was one of a number of young right backs linked with a move to the Emirates Stadium, as the Gunners are also believed to be pushing through a whopping £16m deal for Southampton's Calum Chambers. This suggests that they still see right back as an area of concern, but do they really need another?
Debuchy turns 29 before the end of the month, so Arsenal may only get three or four years of top level service from the French international. Having a ready-made replacement would certainly save Arsenal from scrambling to find a right back – as they did this summer – but Jenkinson was thought to be the eventual right back of the future.
The former Charlton Athletic defender, 22, started just eight games last season, and with the likes of Newcastle United and West Ham United both looking to sign him, Wenger may be ready to part ways with the England international in order to sign someone that he considers to be better equipped to start in the future.
Chambers may be seen as that player, and whilst this surely spells the end for Jenkinson, Arsenal should only be signing another right back if Jenkinson does leave. There are other positions in the team that should take priority, such as the centre of defence, central midfield and in attack, whilst the addition of another goalkeeper should also come before adding another right back - particularly for £16m.
Missing out on Manquillo is far from disastrous for the Gunners, but now we will see how much trust Wenger has in Jenkinson with his pursuit of Chambers.
