During this EURO, there are certain players who have raised their transfer stock by performance in this tournament so that being said...the players who I think will be in league for transfer moves after EURO will be: Patrik Schick (Czech Republic) Denzel Dumfries (Netherlands) Roman Yaremchuk (Ukraine) Andriy Yarmolenko (Ukraine) Xherdan Shaqiri (Switzerland)
From our side: Gains from a low value Tomas Holes, went from the bench against Scotland to being the 2nd best player after Schick so far, he is in his prime years and plays in Czech league so may be a Coufal level value for a team that needs a versatile defensive midfielder. Tomas Vaclik, he's a veteran free agent and was already getting decent attention before a few strong performances. Gains from a high value Patrik Schick - being top scorer can only help, but Schick has always been a recognized talent with high value... higher than his club productivity has really earned.
There were some England rumors before his move to Leverkusen, but honestly he's in a tough spot transfer value wise. His talent is very easy to spot and keeps his value somewhat high, but his club productivity just doesn't fit the price tag.
He struggled at Roma, but he's got ability and at these Euros he has hit a good spell of form so far. Spinazzola, Locatelli, Pessina of Italy have made a mark. I think Berardi did well up to the Austria game where he was found out for his limitations. Tactically it didn't work with him and Barella both at odds with what Mancini was trying for.
Let us simplify it. You play for Atalanta, your stock has risen - Maehle, Pessina, Gosens, Freuler, Pasalic, etc. etc. Biased but a lot of Serie A guys have shown well. Few outside of Italian league fans would never have heard of Spinazzola, Locatelli, Berardi, Damsgaard, Muldur, Kulusevski. Outside of my obvious bias for Serie A: Haris Seferovic (Switzerland) Breel Embolo (Switzerland) Steven Zuber (Switzerland) Glen Camara (Finland) Denzil Dumfries (Netherlands) Xaver Schlager (Austria) Christoph Baumgartner (Austria) Konrad Laimer (Austria) Stefan Lainer (Austria) Patrick Schick (Czech Republic) Josip Gvardiol (Croatia) Nikola Vlasic (Croatia) Dominik Livakovic (Croatia) Billy Gilmour (Scotland) Kalvin Phillips (England) Alexander Isak (Sweden) Laszlo Kleinheisler (Hungary) Attila Szalai (Hungary) Willi Orban (Hungary) Tried to keep it limited to under 30 players.
IMO, Chiesa was the MVP of this tournament. I don't know if his transfer market value will rise as much, but he was often the player who gave Italy that extra bite and energy they needed to unlock their matches and go through the knock out stage looking like deserving champions.
