Spain laboured to a narrow 1-0 victory over Tunisia in an underwhelming World Cup warm-up in Krasnodar on Saturday.

The 2010 champions remain unbeaten under coach Julen Lopetegui, who took over 20 matches ago after the Roja's elimination from Euro 2016 in the last 16 at the hands of Italy. Iago Aspas scored the only goal against fellow World Cup qualifiers Tunisia seven minutes from the end.
