I really can't see what everyone's seeing in Paredes, in fact I prefer Strootman in his current form.
our failures so far can be blamed on Spalletti (especially for insisting on playing Szczęsny, who was the second main reason we crashed out of CL) and our mercato, which some were giving an 8/10 for some reason after siging Peres. I think it was Primo who asked if we weren't going to make any panic buys at the end of the season, and back then I wanted to tell him that we've already made them earlier, we signed Rui, Juan, Vermaelen and Fazio (but I did not get my account back then ......... I still don't have my original account back).
you look at our squad and we've lost a very decent young LB because we did not want to pay a couple of millions and got ourselves an old barely adequate one instead, we have many choices in central defense but most of them are very weak ones, we have no alternative to De Rossi on the roster (again I'm not drinking the same Paredes kool aid not to mention that his defensive style is just a red card waiting to happen, which is ironic when you consider it) and we have no alternative to Dzeko on the roster (a sub not an alternate way of playing). we brought Iturbe back, God knows why, and we let Sadiq go. and yes, losing the player with the best assists stats of last season while playing virtually the same tactics without replacing him did indeed affect us.
you couple all of this with Spall's baffling subbing and strategy choices and you get the mess we're in now.
also, I don't mind playing SES as long as he's played as an out and out attacker in Dzeko's place with Salah and Perotti flanking him.
