Ross Barkley will remain at Sheffield Wednesday for another month.
The midfielder joined the Championship outfit on loan last month and has made seven appearances for the Owls so far, scoring his first senior goal in the process.
The 18-year-old will now remain at Hillsborough as he continues to gain vital match experience.
Wednesday manager Dave Jones has spoken highly of the Blues' youngster.
He said: "Ross has got better and better since he came here.
"The lad has a very bright future and playing games in the Championship will certainly help his development."
