Tek has had good days with us, pointless to deny that, even had a very long period where he was solid and the least of our worries and that was about around the time he initially replaced Buffon but as time went on we could see how his shaky and mistake prone mentality shone through as soon as the team itself started to decline the past few seasons , thing is that yesterday wasn't a one off, he's had plenty of blunders in the previous season aswell which is around the time his decline started to be apparent,both with us aswell as with the Poland NT... yesterday was just another confirmation that he might actually just not be good enough anymore to start for Juventus, that much is obvious.
Sad part is that we have no adequate replacement, Perin inspires just as little confidence, also i see others talking about Keylor Navas being a good option to go for as our main GK like wtf, the guy has just as many blunders to his name, most of them copy-paste to the one Tek made on the first goal, has maybe even more overall in his career, don't get me wrong, he a good GK all in all but not much better or more solid than the high wages polish headache we already have around, the costarican was always the weak link in the two top teams he played for before despite the success for example at RM where anyone that paid attention would realise that the team won everything in spite of him and not thanks to him, so definitely not the guy i'd want around, altough he might have a stronger mentality than those that we have now we would still hardly get anywhere far with him.
I am no expert but if the GK is going to be a guy allowed to make silly mistakes than i'd rather just bring a young up and coming GK and give him the nod, at least there would be some upside and growth to expect from him while he matures, heck we could even cash in on him if he doesnt get better whitin 1-2 seasons and and just look for another one in line to test out rather than invest again in someone that has no resale value and high wages while underperforming.
