The best situation today is that Poland and Wales got a big win and of course this is a good thing before they meet because this will certainly bring some positive impacts, especially in terms of mentality and a strong desire to win.
I think the current situation allows an interesting thing from the match later because although in terms of statistics Poland can always win against Wales but of course Wales also does not want to repeat the defeat again and again especially when their spirit is very good now after a big win against Finland.
Wales no longer have Bale and Poland had Lewandowsky but the striker is older and if in previous tournaments (World Cup, Euro) he could no bring Poland to far, it is unrealistic to think he will be able to do it in Euro 2024.
I don't feel World Cup or Euro will lack of something if Poland or Wales can not join it. They are not strong and competitive enough to go far in World Cup and Euro. Wales even did better than Poland in latest Euro tournaments.
A single striker and already old like Lewandowsky can not easily help his team to win if he does not receive enough good support from his team mates
Actually in this case there is a star player or not in the end it is not a guarantee even though what you say is true when there are several players who can be used as a reference such as Lewa in Poland it will be very good but in the end in other conditions a team cannot depend on their fate on just one player in a match as well as for now because it would be ridiculous if they only relied on Lewandowski alone and we also become unobjective in judgment if we only look at Wales with Bale or Poland with Lewandowski alone.
There are still some players who are very troublesome for these two teams apart from Bale and Lewandowski because seeing now the Welsh players also have good flying hours especially when in the EPL and Championship competitions because seeing from the current Wales squad list almost all are and play in the highest caste and second caste competitions in the EPL which can be a good capital for them.
The presence of star players will indeed be a good indication for a club but on the other hand cooperation and chemistry can sometimes destroy it because when Wales do not have players who stand out too much they will do something else where teamwork becomes a goal to win and this is still possible to happen.
Although on a h2h basis now they are still very different compared to Poland who have always excelled in every meeting but now there must be an improvement and there is no way Wales want another defeat in this match.
