Arsenal boss Arsene Wenger was full of positive news ahead of Saturday's away game against Burnley.
Midfielders Abou Diaby, Mikel Arteta and Jack Wilshere join defender Mathieu Debuchy in making their long-awaited comeback in the squad with goalkeeper Wojciech Szczesny also set to be back on the bench after missing last week's game against Liverpool with a rib injury.
"They [Abou Diaby, Mikel Arteta and Jack Wilshere all] came through the game on Tuesday well," Wenger said.
"They were at a good level physically and they should all be available from now on until the end of the season hopefully.
"[Mathieu] Debuchy is alright.
"I can only play three players over 21 [in the under-21 league] so he is physically fit and ready. He lacks a bit of a competitive edge but overall he has no medical problems.
"He [Wojciech] Szczesny has a chance to be fit this weekend. [Alex Oxlade-Chamberlain] is still out for at least two more weeks.
"It's a thigh problem [for Laurent Koscielny], a little hip problem linked with the thigh. He will have a test today to see how far we can go with him.
"He had a scan yesterday and that looks quite good. The real test will be outside today.
"Everybody else seems to be available."
