Di Matteo says Chelsea have to tighten up

LONDON (AFP) - Roberto Di Matteo has hinted strongly that Chelsea may abandon their attacking style in favour of a more defensive mentality after their 2-1 loss at West Bromwich Albion.

The Chelsea coach is concerned by his team's slump in form after seeing the European champions take just two points from four games and relinquish top spot in the Premier League.

And with a crucial Champions League game against Juventus in Turin on Tuesday evening followed by a Premier League meeting with Manchester City at Stamford Bridge next weekend, Di Matteo says it is time to tighten up.

Chelsea's midfield trio of Juan Mata, Oscar and Eden Hazard have been lauded for their contribution to the team's expansive, attractive style this season.
