The goals numbers he approaching are historical, and many are rightfully praising it, but there some very important areas that increase his standing for me and push him to the forefront of the POTY award:
1) Besides running away with the goals title, he is currently tied for 3rd in the league for assists! This means he has as many as Silva, Alli, Pogba, Mkhitaryan and is ahead of other like Eriksen and Mahrez.
2) This is his first year in the league and it probably took him a month or two to really get acclimatized to the league. Think of all those chances he was getting earlier in the year where he was basically scoring 1 in 3 or 4. His ability to get into those scoring positions is truly world class.
3) Similarly, his conversion rate seems to be picking up as evidenced by his 4/4 tally yesterday. For comparison, Kane has taken 162 shots for his 24 goals while Salah has his 28 with only 118 shots.
I still think Suarez edges him for overall play, but I wouldn't be surprised if he passes him in the next year or two. Also, I'm not saying he's going to continue scoring 30+ goals a year for us, but it wouldn't surprise me and as long as he stays healthy and 20+year seems almost guaranteed based on the way he and our team plays.
