i think barring suarez, they were all terrible signing, i feared every time downing was linked with us , he's just that typical midfielder who can only do it at small clubs, i'd never even heard of henderson and charlie adam, well badly adam. Caroll is an okay player on his day, but his day is every 8 or 9 games, none of their prices helped but they were all terrible signings, worse than what rodgers has bought so far imo.
i don't think sturridge and coutinho will turn out to be good signings either, sturridge is average who has these purple patches and i've already seen signs of coutinho being bullied in this league. people always use excuses like mata and silva with regards to lightweights overcoming the physicality, but these are really special players, coutinho isn't close to that league. I was just stating how they look to be good signings atm because of how well they've started, but like you, i think they will only turn out to be a bit better than average.
