Iraola's side struck twice in quick succession in the first half, with Pascal Gross's own goal followed by Isak's latest strike.

Isak has netted six times in seven league games this season and has three goals in his last four matches.

After a turbulent debut season following his acrimonious move from Newcastle, the Sweden striker is finally beginning to repay his £125 million (US$167 million) fee.
