He's better than Niasse, Lennon (and Mirallas).
We're not going to get a Kane, or Sanchez (just yet).
Hes 28, fairly proven, and will get us goals and give us an actual threat of pace. So if his fitness is kind to us, then hes a good improvement for our attacking options, imo.
Sorry to all those who are expecting Messi, but it's a yes from me.
