dude if you are using uptade, you have to give time to settle in. in real life i dont like suarez but he is excellent in game. just give him 1 year to adopt premier league.
i signed ganso about 30mil dollar, in my spurs save 2nd season. he doesnt perform well in his first season. but now he is brillant.
note: places shots maybe helps him to finish opportunities easily ? he just gets forward runs ppm.
I fine he's a little under-performing as well, don't sell him though, perhaps put him as a sub and slowly bring him into a first team role. If you need a replacement get Carlos Tevez, usually he's available at around 11m.
thanks for the replys everyone i shall keep him see how he does next season but i need to sign a poacher as a good back up cuz ngog doesnt do it for me any ideas who thanks
