The 20-year-old trained with the Irons as a youngster but opted to join the Emirates Stadium outfit once both London clubs made him offers.
Arsenal winger Alex Iwobi has revealed he could have joined West Ham before opting for the Gunners.
The Nigeria international burst onto the scene last season at the Emirates Stadium, and has become a regular in Arsene Wenger’s starting line-up.
But the 20-year-old has now admitted that he also trained with the Irons as a youngster before opting to join “bigger club” Arsenal.
“Arsenal and West Ham were interested in me and Chuba [Akpom], so we were training with both clubs for three years, because we were scouted at six and you can’t sign until you’re nine,” he told reporters.
“I decided to sign for Arsenal because I supported them back then and I always saw them as the bigger club – no disrespect to West Ham.”
