Nottingham Forest suffered a 1-0 defeat in their second pre-season friendly against La Liga side Valencia.
The home team scored the only goal of the game shortly after the break thanks to quick reactions from young midfielder Javi Guerra following a raft of half-time changes.
Steve Cooper's men struggled to create many big opportunities against their Spanish opponents who are coming off a tumultuous season that included three managerial changes and a 16th-placed La Liga finish.
Forest's next game sees them face fellow La Liga side Levante on Saturday morning at the Ciudad Deportiva de Paterna which hosted Tuesday's tie.
