Injury prevented Wilshere from playing with Henry last season, but he is desperate to see his hero join Arsenal on loan again next month.
"It would be great to have Thierry back," said Wilshere. "He is a legend."
The England star, who turns 21 on January 1, said: "Growing up, I watched him. He's the best striker I've ever seen and to play with him [after missing out last season through injury] would be amazing.
"He made a difference when he came last year. He scored at Sunderland and against Leeds.
"And I think Thierry just gives a buzz to the whole place.
"The fans love him. All the staff here, the ground staff, the medical staff, they all love him.
"He's a legend. I think to have him around would give the whole club a lift."
