Cape Town - West Ham United midfielder Jack
Wilshere admits he is determined to show Arsenal what they missed out
on, when the two clubs meet on Saturday.
Arsenal allowed the 26-year-old's contract to expire at the end of last season, which resulted in him signing for the Irons as a free agent in July.
The Englishman was an Arsenal player for over 10 years, having come through the Gunners' youth academy, and he is eager to prove a point against his former employers when West Ham visit the Emirates Stadium on Saturday.
Wilshere told the Hammers' match-day programme: "First of all, I've got to concentrate on football and I quite fancy our chances. I obviously know them really well.
"They've got a new manager, but I know the players, so hopefully it'll be a good time to play them.
"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 play against your parent club, but it's one I'm looking forward to.
"It's down to me to prove a point to Arsenal that they were wrong to get rid of me."
