Traore, who joined the Gunners from Monaco's youth system in 2006, will ply his trade at Fratton Park this season after completing a loan switch last week.
The French under-19 star has made just three Premier League appearances for the London giants, partly due to the imperious form of compatriot Gael Clichy. Hence, he leaped at the prospect of first-team football on the South Coast.
The 18-year-old will make his Pompey debut against the Red Devils tonight, slotting in at left-back in place of Icelandic veteran Hermann Hreidarsson.
And he is eager to impress Wenger by denting United's title ambitions.
“Obviously I had a chat with Arsene and he is going to be watching,” Traore said in The Sun.
“I will speak to him after and some of the players, so I will be doing my best to get a result.
“This is a good chance to prove myself. Harry said he believes in me and I need to be strong.”
