Jurgen Klopp on Diego Costa: 'If other supporters love you it is not a good sign'

Liverpool manager Jurgen Klopp is wary of Diego Costa's "world-class" talent as he prepares his team to face up to the in-form striker.

The Spain international scored twice against Swansea on Sunday to take his tally to four in as many Premier League matches and appears to have rediscovered his form after a difficult time in Jose Mourinho's last season at Stamford Bridge.
