Real Madrid coach Julen Lopetegui conceded his side were "not clinical enough" after they lost their 100 per cent start to the new La Liga season in a 1-1 draw at Athletic Bilbao on Saturday.

Real were up against it for much of the match, with Iker Muniain sliding the home side in front in the 32nd minute at the San Mames before substitute Isco saved Real's blushes in the second half.
