18M is a lot of money!! Sanogo, Fierro, Ozstrolek, Loic Nestor, Romario, Vrsaljko, Badelj, Niang, Yttergard Jenssen, Willian, Douglas Costa, Sigurdsson, Kara, Sebastian Toro, Nika Kvekveskiri, vaclav kadlec, loucas moura...all young players you should consider signing.
Yes i would definitely consider buying Kara if you can he's world class and can play as a CB stopper or as a DM, I'm on my second season with Norwich too finished 5th in my 1st season using Raikaan007's ama-zing tactics and 1 of his training schedules which has improved my players a lot. Daniel Ayala has become good so has Bennett and Pilkington
