The Gunners have had an impressive summer which has seen them backed to make the top four this season and secure the return of Champions League football.
And it’s not just signing players where they are impressing in the transfer market.
Former youth star Jeff Reine-Adelaide has clinched a move to Lyon from Angers for an initial fee of £22.8million.
The deal could rise another £2.3m in add-ons with the Frenchman signing a five-year contract.
Upon selling Adelaide to Angers for £1.4m last summer, Arsenal inserted a sell-on clause worth 20 per cent.
That will see them net around £4.5m from the deal, which acts as a nice consolation for the small fee they sold him for nearly 19 months ago.
Arsenal also had the option to match any offers for Adelaide, something they included when he left the Emirates Stadium.
Yet they passed by the opportunity given that the English transfer window is already closed.
Reine-Adelaide revealed in June that he was told by Unai Emery there would be limited opportunities and therefore it was best he found a new club.
“I was young. It was complicated. There was so much competition that it was difficult to get into the coach’s line-up.
“He [Emery] told me that the club did not rely too much on me. I took a blow, but Angers was on the lookout. It was a new chance, a new beginning.
“The train does not pass often and I was happy to get back in the right car.”
Arsenal brought Nicolas Pepe, Kieran Tierney, David Luiz, Gabriel Martinelli and Dani Ceballos through the door before the August 8 deadline.
William Saliba also joined for £27m from St-Etienne but has returned to the Ligue 1 club on a season-long loan.
Emery’s men got their campaign up and running with a tricky 1-0 against Newcastle on Tyneside with Pierre-Emerick Aubameyang scoring the goal.
