Chelsea defender Antonio Rudiger has suggested that Olivier Giroud, Alvaro Morata and Willian are not doing enough to help top-scorer Eden Hazard with goals this season.

Newly-appointed manager Maurizio Sarri has impressed with his attacking brand of football at Chelsea and remains undefeated in the Premier League, with Hazard alone scoring six goals so far.

However, after their 1-1 draw against Liverpool at Stamford Bridge, Rudiger has suggested that the Blues' other forwards must help out the Belgian if they are to continue their form.

"We need to learn to kill matches," Rudiger told the Evening Standard. "It's not only on Eden's shoulders. We need the other players to help him with scoring.

"He has been doing his job very well again, but the other guys must score too – Giroud, Morata, Willian have to score. As a team all of us have to provide more goals, the defenders as well.

"At the end of the day the best scorers are Hazard and Pedro, but with the quality of players we have on the pitch, it's not too good."

Sarri's side will hope to continue their unbeaten run when they face Southampton away in the Premier League on Sunday.
