Arsenal boss Arsene Wenger says Wojciech Szczesny will face FA Cup opponents Middlesbrough tomorrow.
David Ospina's fine form has kept Szczesny out of the side but Wenger says he's ready to return.
"[He has responded] very well," the manager said. "He's very good in training. He responded in a very determined and focused way.
"He's ready to play. At the moment I feel I left Ospina in because he has done well but Wojciech is completely ready and has impressed in training."
