I posted this in the tactics thread but I guess this applies to transfers aswell.
Realistically if we wanted to stick to the 3-5-2 and implement it in Europe with an actual hope of success then we would have to make big changes.
First of all, Licht is a fantastic RB and Asamoah looks to be a dynamic, energetic CM. But NEITHER of these two players have the offensive qualities neccesary to play LWB and RWB in Europe. People will argue 'But they're defensively solid' blah blah blah etc etc.
Well we've all seen infront of our own eyes how much that's benefited us in the CL
Besides, it doesn't matter how 'defensively great' they are. Because when we need a goal and our wing backs press high up the pitch, we eventually get countered and I don't care how good you are at making a challenge, it's going to be quite difficult dispossessing the player who's 40 yards infront of you. It makes no difference basically.
So, two new attacking wing-backs. Who also put in a decent shift. Cuadrado and Criscito perhaps
Second of all, we can stick to having a Regista although i'm not a fan of this because replacing Pirlo would be like selling Vidal and hoping to find an equal replacement for him. There are none, so no matter what if we stick to a Regista we'll eventually take a dive in quality.
The better option would be to buy an attacking midfielder. That way we can still have a real creative force in the team without trying to replace the irreplacable. Makes sense to me. Of course the formation would resemble more of a 3-4-1-2 but that's minor details really
Last of all, we really do need a goal scoring machine if we're serious about mounting a challenge in Europe. Llorente or Tevez (Probably Llorente) would have to take a seat. I'm more than ok with that. Tevez might not be a real threat in Europe but he will cover a lot of ground and help take pressure off of whoever he was partnered with.
So basically, if we want to stick to 3-5-2 and improve significantly it won't be any cheaper (One could argue it would be even more expensive) than changing our system. Or... we buy another few depth players and repeat this season over & over again.
