He tweeted: “After 3 + 1/2 unbelievable seasons, working with amazing people, I am now starting a new chapter.
“It was a very difficult decision, leaving Leicester, but I had to take an opportunity that doesn’t come round often.
“I only wish the best for Leicester in the future and will always be eternally grateful to them for getting me to where I am.”
It is understood than Ben Wrigglesworth will see his salary considerably increased at Arsenal, he will now join Rob Mackenzie as the second man to leave Leicester’s scouting team in less than a year after Mackenzie joined Tottenham last year February.
