It's kinda unorthodox signing for us, because of his flashy looks and bold personality, but also a curious one.
The physics and technical skills are there, so everything else is in Tito's hands. If his work is success, we could see a new, a lot of better Song than we know. I don't have nothing against this signing. Surely it looks as a gamble, because of his reputation of undisciplined and error-prone player (at least it's what they say), but we could be adding something good to our squad. Or not. Time will tell.
We had two strong african guys in our midfield in the last couple of years and both of them served us well. Let's see how it goes now.
As about the money - it's always kinda subjective, because different people look at the market in a different way.
