Alex Iwobi has agreed a five-year contract with Marco Silva’s men, in a deal worth £40million on Thursday.
The Nigeria international has been a Gunner since joining the academy 15 years ago. He came through the ranks and made his senior debut in October 2015.
Iwobi went on to make 148 appearances, scoring 15 goals winning one FA Cup and two FA Community Shields in the process.
Reactions Trail Iwobi's Transfer to Everton
Former Super Eagles captain, Kanu Nwankwo (London)
"Once a Gunner, always a Gunner. We are proud of you Alex Iwobi and will continue to support you. Good luck with your new club.”
John Nwodo (Idimota Lagos)
"I wish Iwobi good luck! It seems to me as a good move, with Unai Emery new signing, Iwobi may struggle in getting playing time, so it is better to go to Everton to continue his development in the game."
Benilu Adoni (Abuja Nigeria)
I think going to Everton is a demotion. With a player of his age I will prefer him to be in trophy contender team and graduate to PSG, Man city or Barca.
Eno Iniabassey (Uyo, Nigeria)
"There's something wrong, anytime a serious manager come to rebuild a team, Nigerian players in that team are often off loaded. I guess Iwobi has sensed he may fall excess in Emery's plans this season."
