Underwhelming so far, as we all know he's extremely talented but few things stop him from being able to show he can use that talent to become a consistent, world-class player. Little doubt that the environment of changing managers and lack of stability has not helped him, his personal issues contributed to that too, and his work ethic is somewhat questionable - wouldn't call him lazy, but in order to be the best you need to give 110% every day, and I am not sure if Tony is doing that.
Nevertheless, my hopes for him are still very high and this guy brought me so much joy I can't help but love him. Turning 24 this year though, so he can't be really judged by his potential and talent, he's a mature player that has to start delivering consistently and stepping up when it matters. Next season could and probably should be decisive for him - and I truly wonder how Ole plans to play him.
