Romelu Lukaku has hailed his own 'dominant' performance against Arsenal after opening his Chelsea account.
The Belgian striker, a £98million summer signing from Inter Milan, brushed off Pablo Mari with consummate ease before tapping home to score his first goal for the club in the Blues' confident 2-0 win against the Gunners on Sunday.
But Lukaku admitted that despite satisfaction in his side's performance, they now need to keep improving in order to challenge in the Premier League given the division's competitiveness.
He said: 'I'm very happy with the way we played, we dominated, could have scored more but coming here with this performance we have to continue like that.
