Although Cavallini impressed during the U-23 tournament, and short after that he signed a professional contract, he needs yet to get some playing time with his club first team. These days he's not even in the bench, so unless he starts getting some playing time, it would be unfair IMO to call him instead of other players.
Someone I'd love to see is DiChiara but it seems he's struggling to get his place with the first team too. Too bad (I wonder if that's the reason uno stopped to post here in the forum).
Right now I think REB will be called up Cavallini needs some first team experience And I think he will get some in due time.
Interesting that Piette was the only one of these guys called up after a pretty decent tournament. Although I still struggle to find someone on this roster right now and say a replacement from the U-23s would be better.
Maybe Henry or Fresenga for Ledgerwood.
