Under-fire AVB demands '300%' improvement

Andre Villas-Boas insists Chelsea need a “300%” improvement if they are to avoid more embarrassment in Tuesday’s FA Cup fifth-round replay at Birmingham amid increased speculation his job is under threat.

Villas-Boas conceded himself he was under extra pressure after a 1-0 defeat at West Brom yesterday provided a further dent to Chelsea’s hopes of securing Champions League football next season.
