Manchester City defender Kolo Toure insists Arsenal are on the right track to be challenging for titles again.
Arsene Wenger's men have not won a trophy since 2005 but Toure believes it is just a matter of time before they end the drought.
He said: "Definitely - they have young players working really hard, they played very well.
"It's magic - Mr Wenger brings in any player and makes them better. Credit to him because he's a fantastic manager.
"He knows how to see young promising players and that's a great quality for him.
"(Emmanuel) Frimpong was fantastic, Oxlade-Chamberlain was good as well.
"All of them were fantastic - they made us work really hard but at the end we had the killer goal."
