He failed to see the best of Nicklas Bendtner during nine years at Arsenal, and Arsene Wenger will come up against the Dane on Tuesday.
Ahead of Arsenal's EFL Cup tie with Nottingham Forest, Arsene Wenger says he was surprised to see Nicklas Bendtner sign a two-year deal at the City Ground.
Bendtner spent nine years at Arsenal, making 171 appearances without ever doing enough to fulfil his self-proclaimed wish to be the best striker in the world.
Released in 2014, Bendtner had a brief spell in the Bundesliga with Wolfsburg, before arriving at Forest earlier this month.
