Unai Emery said that stuttering Real Madrid must find balance without Cristiano Ronaldo, but the Arsenal boss has backed Julen Lopetegui to do so.

All-time leading scorer Ronaldo left for Italian champion Juventus in the off-season and Madrid has struggled to fill the void following four consecutive matches without a goal.

Madrid has lost three of those games, including last week's shock 1-0 LaLiga defeat at Deportivo Alaves, increasing the pressure on under-fire head coach Lopetegui.

Emery, however, is confident Lopetegui – who replaced Zinedine Zidane at the start of the season – can get Madrid back on track.

"Real Madrid must find balance without him and they need time to adapt. However, I think Julen will find it," former Sevilla boss Emery said.

Emery added: "We cannot answer for Julen, but when it happens to me, I try to be patient, but it is difficult to ask for patience in football. I'm sure the goals will come for Lopetegui."
