Jack Wilshere is determined to prove Arsenal were wrong to release him when he revisits his old club with West Ham on Saturday.
The 26-year-old spent 11 years at the North London club before joining West Ham on a free transfer in July, and he is set to make his first appearance against them at the Emirates Stadium this weekend.
Wilshere played on loan at Bolton Wanderers in 2009-10 and at Bournemouth in 2016-17 but has yet to experience lining up for Arsenal's opposition.
He told West Ham's matchday programme: "It's down to me to prove a point to Arsenal that they were wrong to get rid of me.
"It'll be a strange one for me as I was never able to go there and play when I went out on loan as you can't play against your parent club."
West Ham have suffered a dreadful start to the 2018-19 season, slipping to a 4-0 defeat at Liverpool in their opening game before being beaten 2-1 at home by Bournemouth.
But Wilshere indicated the Hammers are confident of heaping more woe on Arsenal, who have yet to earn a point under new manager Unai Emery.
"It's one I'm looking forward to," said Wilshere. "I quite fancy our chances."
