Arsenal hero Martin Keown is impressed by the early impact at Cardiff City of Gary Medel.
The Chile international was excellent for victory last Sunday over Manchester City.
Keown told the Daily Mail: "There's an adaptability in the team. Key to a lot of the good work is Gary Medel, Mackay's £9.5m signing from Sevilla. He's nicknamed the Pitbull and you can see why as he snaps at the opposition's heels. He protected the back four when necessary but also joined Gunnarsson going forward."
