So, what did we learn form yesterday? Not much. Just that MP's system is gradually being instilled into the players. The left right and Centre of the top 3 interchange, the forward drops back and links up. More movement and sharper passing.
I know that Celtic didn't bother much.
Celtic only had 2 players that were in the team that lost to warsaw in the 1st leg of the CL qualifiers.
The rest were youngsters.
However we had Mason, Bentaleb, Frdericks, McGee, Fryers, Veljkovic and Kane - who are our youngsters, and were without Walker, lloris, Chriches, Vertonghen, Paulinho, Demebele and Chadli.

So, basically it shows that Celtic have no depth. If they only have 15 or so players and cannot find any others to put up a fight then their future looks bleak.
