I have heard of them rules yes.
FFP is a farce, we are the only club in this country that bothers with and adhears to it, yet we are the ones who get punnished, we should do what all the rest do and ignore it, what is the worst they can do?, ban us from the pathetic CL?...oh well, no harm done there......also UEFA (that bent organisation) stated that FFP would be relaxed this summer due to Covid, and as such it enabled sides to spend whatever they felt they could afford and want to.
No fans is a blow, and stupid still that no fans are allowed in stadiums, when they have them in other sporting arenas around the globe, but that is costing sides lots of money yes, hence why FFP rules have been scrapped for this year.....we still have 2x foriegn slots available as well.
I cannot remember the worst window Cook oversaw, but it must be the one where Kolo Toure, Gareth Barry, Emanuel Adebayor, Joleon Lescott, Carlos Tevez etc all rocked up in 2009/10 season, as the next one was the best this club has ever had since HRH Sheikh Mansour arrived, seeing us bring in the likes of Silva, Yaya Toure, Kolarov, Boateng, Milner, Balotelli and then later that year Edin Dzeko.....as the next one (his final one before he left) saw us attract the likes of Gael Clichy, Samir Nasri and Sergio Aguero to the fold, so hardly a bad window then either, when all 3 of them played major roles in us winning our first League Title, or did you mean his very first one in 2008/09 season when he helped the club acquire the likes of Vincent Kompany, Pablo Zabaleta, Shaun Wright-Phillips, Craig Bellamy, Shay Given and Nigel de Jong amongst a list where, we also got Tal Ben-Haim and Wayne Bridge........you will have to let me know which is worst one is?.
He left in September 2011 by the way, so if your going to be blaming him for the signings AFTER winning that title, then that falls at Marwood's door, all after that is the latest clown of a DoF we have.
I would take Garry Cook's worst window and shopping spree experience ahead of Txiki's best any day of the week
