Chambers seemed to cower when faced with a bullying Benteke tonight. Benteke didn't get a sniff in the FA Cup final, but tonight he made Chambers shrink and Wenger must surely be relishing Koscielny and Per's returns. Paulista was jittery, too.
The pair have only played together once before - in the Emirates Cup, no less - and they were over-reliant on Cech.
Neither was given much protection from Coquelin, though. He was overwhelmed and overworked by Liverpool's advanced playmakers.
