Honestly, it doesn't matter who we put out left. Baines will simply not get forward.
Klaassen has a lovely first touch, has great movement, but it's wasted out there as is Siggy where he's there, too. At Ajax, he has width and an active CF.
Davies did well because he at least had Cuco TRYING to get forward, even if he is completely irresponsibile when he does it.
