Not sure where you have been for the last 3 years or so but we have blown away every single rival in the PL with our Midfield. We also did the same to some of the best teams in Europe too. At our best our midfield dominates the oppo, this has been the case in almost every game I have watch Spurs play in the past 3yrs or so.
This season we have a mass of injuries to some of our best players, 9 of 11 first team players who didn't have a pre-season and we have only played a couple of "home" games all season (to which these home games are now being played in an atmosphere that is akin to a behind closed doors game).
Sissoko isn't our first choice midfielder (CM or DM), this is because he's not that good a player but when called upon he has stepped up and we have continued to win games. This should be recognised but no you seem to feel it's worthy of some kind of ranker and stomping and stamping of feet. I simply don't get this at all. Why are you expecting him to be Busquets or some such? Think of what Wimmer did when he stepped up when Vertonghen was injured, or Davies last season when Rose was injured/wanted out. The team is even more depleted now than it was back then too.
Again you bring up Tripper when the topic is not Trippier.
You are bringing up other midfielders "that have blown away the opposition" when we are talking about Sissoko, who definitely has nothing to do with that/those midfields. It's like me saying to you we have blown away teams (inc Real Madrid etc) because of Trippier.
I don't agree that "our midfield has blown away all comers over the last three years" I think our success has been about more than one particular facet of the team, and even then I think sometimes (not always) we have achieved things in spite of our midfield's laborious and risk averse nature, not always because of.
But lets not derail the Sissoko thread with how good or bad our midfield has been previously or how good or bad Trippier is.
Even that article you posted acknowledges some glaring basic deficiencies in Sissoko's game. I do not understand how anyone can defend those deficiencies at this level. Basic technique. The guy's earning nearly 5m a year. Again, I don't blame him for his level of competence, or what we are stupid enough to pay him, but to deny it is plain daft, to constantly try to talk him up as something he isn't is also daft - especially when those same people will criticise others ferociously. And to get all pissy with people for calling him what he is, especially those paying to watch his inadequacy is daft. And I firmly blame Pochettino for playing him.
As an aside - did you see the discussion on MOTD Saturday night with Gullit talking about 433 and how small, dextrous, (and sometimes tenacious) midfielders are the future?
