Bacary Sagna has hailed Arsenal youngsters Nico Yennaris and Francis Coquelin.
Both players featured at right-back as Sagna recovered from injury.
"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.""They're amazing," Sagna told the Official Arsenal Matchday Programme. "They just play and don't worry about anything.
