<p>Onana, usually the midfield destroyer for the Belgians, was shifted to centre ‌back for the start of the friendly in Rijeka, ‌which Belgium won 2-0 with a morale-boosting performance.</p><p>It was a surprise ‌switch from their traditional 4-3-3 formation, but one that had ‌been planned to see whether it might be an option at the tournament in Canada, Mexico and the United States.</p><p><strong>"I felt good in ‌that position," Onana told a press conference on ⁠Wednesday. "The partnership with Arthur (Theate) ‌and Nathan (Ngoy) went quite well. They carried out their roles very effectively ​too. For a first full dress rehearsal, this was certainly not bad at all.</strong></p><p><strong>"I've played there a few ​times before. The team comes first. I'm a midfielder, that's my favourite position, but if they need me at the back, ⁠I'll do it. ​Even if the coach needs me up front as a striker, I'll play there," Onana told reporters.</strong></p><p><strong>"I feel most comfortable in midfield, and I believe that one day I can be one of ‌the very best players in the world in that position. The World Cup is the priority right now, though, and if I have to play in defence, I'll do it without complaining. I felt good there yesterday as well."</strong></p><p>For coach Rudi Garcia, the experiment went well.</p><p><strong>"This gives us more variety in our play, especially because we have many players who are versatile enough to operate in this system," he said.</strong></p><p><strong>"Of course, ‌there are still things that can be improved. But at least ​we now know that we can use this system ‌to start a match or switch to it during a game and that we can also achieve results with it.</strong></p><p><strong>"Because he is naturally more of a midfielder, it gives us the option to move him around. We saw (against Croatia) ⁠that he has all ⁠the qualities needed to do ‌this job successfully."</strong></p><p>Catch up with their win over Croatia with Flashscore.</p>
