If I were a mod just for one day, ...
there might be a reason behind that you are no mod nor probably never will be.
i could quote some funny guys here to respond to your high rating of tiagos last performance...
the quote would be like "so you are satisfied by mediocrity?" . . .
you sound just like someone who does not know what he is talking about, hell did you even play in a football club for one season ?
it is totally understandable that someone that did never really play football can not judge a players skills or performances if you never really played football. some things look difficult and you will rate someone high for it, even if a football player would say it's easy.
just because tiago was not as bad lately as he was last year does not mean a shit. you can't be serious that you do allow a player to play shit for a whole year and then praise him for 3 decent games.
what does tiago do so great ? you say he keeps us flowing !
did you ever notice, that ekdal does the same ? he has a good vision because it seams that he always knows where to play the ball even before he received it.
tiago still needs his time controlling the ball and running a few meters before he decides where to play the ball and i am pretty sure that we did not pay such an amount of money for him, just for making us "flow" better.
as i already wrote, there are players that do know how to use their skills regardless of the performance of others ... tiago is surely not like that.
you may be satisfied that someone that does some mediocre passes provides us with balance in the midfield. that is ok, but tiago did cost us more than 10 m euro and hell for that amount of money we could get two players that would do exactly the job tiago did for us the last games.
you don't pay 10 m euro for that performances, even if you would erase the memory of his past games last season i am sure everbody would say that he is underperforming (if you measure him on his price).
