In my opinion, Fernando Santos is one of the smartest modern national team coaches. With a team that is not the strongest in terms of composition, he won two titles (the European Championship and the League of Nations) and consistently shows good results. He prefers "reliable" game schemes and this is quite understandable - Portugal beats "light" opponents one way or another, but the team's main competitors are much stronger and you have to use tactical tricks to beat them. I don't understand how you can blame him for bad style of play. He chooses his formation for each match with a strong opponent individually and mostly he succeeds. But we cannot demand that he consistently beat France, Brazil, Germany, etc.
But I'm not expecting him to always beat France, Brazil or Germany. If I lose against these countries I will understand and accept naturally.
But for the range of players that Portugal has, it cannot be accepted that they lose with Serbia or draw with the Republic of Ireland. It's not that these teams don't have quality, of course they do. But the Portuguese team is frankly better.
The problem that often occurs in Portugal is the influence that some clubs and some players' agents have on the football federation. Making good players sometimes not called up or not playing, and then you see players who are not having good performances starting. It's one thing to lose and play well, it's another to play poorly and lose games that clearly should be won.
But it's true, we're at the World Cup in Qatar, and no matter how much criticism or less if you like the style of play, you've managed to overcome the obstacles. I'm glad of course, but I think they could be a little better, that's all.
