Chelsea keeper Thibaut Courtois said Belgium were “outclassed on all fronts” as they were beaten 2-0 by Italy in their Euro 2016 opener.
Sunderland striker Emanuele Giaccherini clipped in a first-half opener and that was added to by Southampton forward Graziano Pelle, who volleyed home in stoppage time to complete an impressive Group E victory in Lyon.
And Courtois was not making any excuses afterwards and admitted Belgium have got to improve ahead of their games against Sweden and the Republic of Ireland.
“We were outclassed on all fronts,” Courtois told Sport Wereld. “Tactically, technically and organisationally we came up short.
“We made the same mistakes as in the friendly games. For the first we did not follow our man.
“This is a big disappointment, because the first match is very important. We could have done a great thing after the draw in the other match.
“The next two games we should be winning. We have to play better.”
Belgium, who are bottom of their qualifying group, will face Martin ONeill’s men in Bordeaux on Saturday afternoon before concluding their Group E fixtures against Sweden in Nice on June 22.
