Bacary Sagna has hailed Arsenal youngsters Nico Yennaris and Francis Coquelin.

Both players featured at right-back as Sagna recovered from injury.

"They're amazing," Sagna told the Official Arsenal Matchday Programme. "They just play and don't worry about anything.

"I was happily surprised with Nico's performance against Bolton back in October - he closed down really well and imposed himself well. He did an equally good job when he came on against Manchester United, and I'm very pleased for him - he's a hard worker and deserves a lot of credit.

"It's the same with Francis, he's a midfield player first of all but he's given his best at right-back and we know that he's very good technically too."
