To be honest, I think it's too early to judge the "transfer committee"
I think in terms of success this year, they were the wrong purchases, but apart from Lambert (backup), and Balotelli (has a track record of success, it was gamble that was worth it at that price) they are all young players, quite a few years away from their prime. Even Balotelli is young, though may have his best football behind him.
I'm sure they could have spent all the money on 2 or 3 ageing super stars, and done better this year, but what's the point.
It's not the Rodgers or FSG way to spend that way, they prefer to look to the future. I think this time they have done so too much though.
Look at Henderson. People thought we were mad paying what we did for him, but last year, and at points this year, he was one of our best players, and probably our future captain.
Lallana, Moreno, Manquillo (if we sign him), Lovren, Markovic, Origi all have their best years ahead of them, and what seems a disaster now might save us a lot of money in the long term.
It's frustrating now, and Rodgers is not getting the best out of them, but I still believe in the system.
What we do need is a solid goalie, as an alternative to Mignolet, and someone who can actually score (maybe even getting Origi from loan would be enough). The rest will work itself out.
