Capable of 25-30 goals yes but outside of his current season in Turkey, which with all due respect is not on a par with the top 5 leagues, he has only done it once in 5 attempts. I do have significant doubts that he would be a reliable goal scorer in the PL along with concerns over his durability given his injury history, something we have ignored in previous deals to our great cost.
Not totally against him but I certainly don't think he brings any kind of guarantee of success and so rather like Chelsea I would want him to sign a team friendly deal with salary tied to bonuses and I also would not want to pay a big fee, maybe 50M max including add ons.
