Olympiakos are extremely poor away from home, we should beat them with any formation.
You can add a 2-0 loss at Malmö to this.
Playing away is always that bit tougher, so what you say wouldn't surprise me, even if I think we should be more adventurous for these next two CL games.
tl;dr - basing our long term formation or approach on this game or the result of this game isn't wise, but it is wise to take the initiative for this game.
Only issue is that it looks like Pirlo is going to be responsible for marking Dominguez. Which pretty much means that their best player is going to have plenty of time and space to do his thing.
Change Perreya with Pirlo and, place Marchisio central.. Olympiakos is going to de defend very deep, and Pirlo won't be able to make his killer pass behind their lines..
- Perreya offers more speed and direct play, and Marchsio offers more cover! We play so slow with Pirlo on the field.
If things wont go as planed i really hope he brings on Giovinco, he may not score many goals - but he creates so many chances!
