See, I don’t think it is unrealistic. As you’ve touched on, he could cover a couple of different positions; even if he jumped ahead of Allen in the pecking order that would have given him meaningful minutes so far this season. There’s also been subsequent chat about Torp’s fitness levels, so there’s an opening as well. It’s an investment that they are good enough to make the step up in time. Personally I’d be preferring someone of that tack to Jamie Allen (and, arguably, Eccles too).
It really boils down to what kind of midfielder FL wants and who would work in the context of the existing set-up.
The problem with SRS just to use him as an example, is that while he can play 6 and 8 he sounds very similar to Grimes in terms of style of play. I wouldn't really want two similar players playing in the same midfield as it'll just make us disjointed and stifle any kind of attacking potency.
The one thing we're missing is that attacking aggression in CM, someone that can unleash a ludicrous pass or pick the ball up in the middle of the pitch and drive forward at pace to either attempt a shot at goal or thread one of our forwards through.
I will caveat the above by saying I've only read reports and glanced at YouTube highlights of SRS, where on first look he does seem quite similar to Grimes, just with better footwork, but he could very well be that kind of player now.
If so then sign him up as the ideal would be to sign someone that can act as a dynamic forward thinking 8 and 6 rather than just one or the other.
Which is the point I've been reiterating for a while. We're better of signing 2-3 quality players which can each play a couple of positions rather than a player per position in regards to the gaps that need filling.
