We lacked a few minutes of concentration to turn the tide of the match,

We made too many service errors. The players who are usually strongest in this element couldn't show their best. I don't think we broke down mentally, but there is definitely still room for improvement regarding concentration.
It's unpleasant to start the tournament with such a loss. This makes our task of qualifying for the finals more difficult, and furthermore, we also lost valuable world ranking points, as Belgium is behind us in the standings.
However, I believe we can get out of this situation and show our best in the next three matches,
