I actually think I'd rather Zinchencko than Tielemans.
Arteta will have a decent read on what Zinchenko can do, and he's a player that I think is ascending. Fewer miles on him, great training under Pep, and he could cover for Tierney.
What of a midfield of the following? Feels balanced, and would relieve a little pressure from being so reliant on our right wing. Only worry, is that Zinchenko and Odegaard don't have great drive to get into the box.
Zinchenko -- Odegaard

With El Neny and Lokonga as back up.
