In Europe these tournaments are big deals for all the top players, not just Pirlo. This is nothing new either. He's consistently talked about how important Euro is to him, so if true, it's not a shock. Big time European players aren't necessarily beating down the MLS door to come here. Euro is a big friggin deal there. How many MLS players will be involved? Very few. Europeans will see Pirlo playing in one of the top tournaments of the world with a storied national team, not only representing Italy but NYCFC too. That could have a very positive impact on our club going forward.
Being in Europe for the Euros is obviously fine. But things like playing in MLS to "stay in shape" only, or potentially missing our preseason or even regular season games to get some token appearances against higher competition as practice? That makes it sound like he doesn't think "Euros > MLS", but rather, "Player > Team."
Maybe I'm paranoid, but I'm coming down from the "we got Pirlo!" high and starting to get nervous our DP's aren't going to work out as well as we hope.
