Id like to see it too, but Marsch seems reluctant to play Etienne as a winger. I get that he gives you a lot less defense than Muyl, but against teams that bunker who cares? Toronto probably wont bunker, so I get Marsch going to with Muyl this match.
No doubt, thats why this is about who plays in Royer's spot, which i think needs to offer more wing-like play since Valot plays his side more like an attacking 2-way mid.
DE7 has 120 less minutes (and several less seasons) played than Muyl with 1 more point of production. And its an eye test thing. The offense flows and has ideas when Etienne is out there, less so when a fullback is up in attack. He needs a little more hunger for goals, but I think folks are being way too harsh on DE for his misses v Philly. Good things happen when he's out there.
What Id really like to see is Tyler at the 10, like in the second leg of the playoffs last season. TFC still runs through Bradley, and I like the idea of having Tyler there stopping their attack before it starts. Move Kaku to the wing and play RZA next to Davis. Muyl or Etienne first off the bench, depending on whether were trying to hold on to a lead or need a goal.
