Late to this one. Fully agree with Shig's opening gambit and the various comments about being played out of position, and also the frustrating inconsistent ones.
if I was ever a manager, heaven forbid, then I hope I'd always find a way of incorporating a luxury player into the formation, because I think every team needs one and I would want the team to express itself and its individual skills/flair. And I know that's not the real world because results keep your job, not entertainment, so this is me just saying my own aspirations for a team.
There's been so many of them over the years, we all know the names. Time was the game's pace was completely suited to them and they flourished. The more recent ones like Le Tissier, while a God at club level because he stayed where it was best for him, were unfortunate to be around at international level as the game went (even more) hard working and formation driven, plus playing for England managers who wouldn't or couldn't tolerate the lack of workrate. Cantona got away with murder because he had a hard working midfield around him and a manager who was prepared to accept the plusses outweighing the minuses.
Sul is our box of tricks, and I think that final bit is where Critch is with him. He's no more a left winger than I am, and I'm 54 and my left foot has always been for aesthetic and balance purposes only. It does puzzle me why he persists with him out there as there are alternatives for the wide left role.
I know I'll get pelters for this, but I actually liken Sul's situation to Joe Cole, a talented and skilful ball player who also had the workrate to go with it. I personally thought he was good enough for England to build a creative midfield around, playing an advanced central position. But it never happened because firstly Lampard and Gerrard's roles were deemed more important to the team's success, and secondly England didn't have a genuine left sided player at the time so Cole got the job and ultimately became about as effective as Sul is now in the same position.
if he's going to be played then Sul's just got to be given the freedom of the park (when we're in possession), understand what's needed of him more when we're not, and get someone to deliver a rocket, thinly disguised as a confidence building love in. The psychologist suggestion above is an interesting one - it's not often I've thought they were of much benefit, but there's something here that's stopping him using his potential and talent. If it's just CBA then that's a shame because he does have it, it's just going to waste at present.
