"Mexico were just tactically better. Their system made our five defenders sit deep and we were swimming in midfield - it was five against seven," he told
Het Laatste Niewus .
"Look, we still put too much on our talents. As long as we don't have a good tactical system, we will have difficulties against countries like Mexico. It's a pity that we have not yet found a solution.
"Of course we play with a system that is in principle very defensive, but it is filled with many attacking players who want the ball.
"Then you have a bit of a problem, like against Mexico. It was a match in which we had very little possession and everyone in a system that doesn't really fit. We now know that something must be changed against such teams.
"But eventually Martinez decides. I think the trainer has to find a solution so that we can avoid such situations as against Mexico in the future."
