Aaron Ramsey has welcomed Jack Wilshere back into the Arsenal team.
But e warns Wilshere, 20, must be given time to get back to his best.
Ramsey told The Sun: "Jack scored a great goal against Montpellier but he still needs time.
"It will take him a while to get his match fitness back along with his full sharpness. People have to be patient with him.
"Of course, he's shown already what he is capable of and I am sure he will be back to his very best soon.
"He had been out for a bit longer than me and had some complications.
"He is a very determined character and I thought he came through everything well and hopefully he can now stay injury free."
