I hope this scout buyer isn't in your competition, because by the looks of this, this scout team have more than enough ability to turn this 4-1 defeat around in the second leg and then go on to win the competition. A similar result occured with a scout buyer that was once in one of my CL competitions a long time ago. He lost 2-0 away in the last 16 and looked like going out but won the second leg 3-0 then went on to win the competition.
All I can think of here is that the scout team has probably set themselves up to play down the flanks with a 4-3N-1-2 formation which would play into the hands of the 4-4-2 classic which is a formation that naturally uses the flanks.
