Thibaut Courtois admits that Belgium were outclassed in their 2-0 defeat to Italy in Lyon on Monday.
Marc Wilmots' side were regarded as one of the pre-tournament favourites in France, but sit bottom of Group E after goals from Emanuele Giaccherini and Graziano Pelle handed Italy all three points.
Courtois was unimpressed with his side's display, and has called on his team-mates to improve ahead of Saturday's clash with the Republic of Ireland, who drew 1-1 with Sweden on Monday.
"We were outclassed on all fronts," said Chelsea goalkeeper Courtois in quotes reported by Sportwereld.
