After scoring 14 goals last term, Kemar Roofe opened his account for this season with a brace

Marcelo Bielsa's Leeds United produced a devastating attacking display to sweep aside Derby County and continue their winning start to the season.

They led inside five minutes through Mateusz Klich's 20-yard curler, but Tom Lawrence soon levelled with a fierce, dipping free-kick.

Kemar Roofe's header restored the Whites' advantage as they continued to pour forward during an open first 45 minutes.

Rams manager Frank Lampard brought Bradley Johnson on at half-time in a tactical switch that did temporarily stem the flow - but Roofe's superbly-struck second and an Ezgjan Alioski header added further gloss to the scoreline.

Ex-Chelsea and England midfielder Lampard, in his first home game as boss, cut a frustrated figure on the sideline as his Derby side failed to back up their late victory at Reading last week.

Leeds were excellent in beating Stoke City on the opening weekend and again caught the eye at Pride Park, with Samu Saiz and Alioski both heavily involved throughout.

Former Argentina and Chile manager Bielsa is well known for his high-pressing, attacking football and already his methods appear to be working well at his new club.

Only a point-blank reaction save by former England goalkeeper Scott Carson kept Luke Ayling's header out to prevent an even more one-sided result.

Patrick Bamford, a £10m summer signing from Middlesbrough, also came on for his Leeds debut late on as the hosts failed to seriously threaten during the closing stages.
