Barcelona boss Ernesto Valverde has sent his side a warning after Wednesday’s Supercopa de Catalunya defeat to Girona.
A goal from Cristhian Stuani saw an experimental side narrowly beaten in Sabadell, and after the match Valverde talked about their Champions League hopes
“What happened to Madrid could also happen to us,” he said.
“It has to serve us to be prudent. We are not yet in the quarter-finals and we have no advantage. A bad day leaves you out.”
The Champions League has thrown up some surprises in the last 16 stage with Ajax beating Real Madrid and Manchester United coming from behind to dump out PSG.
