After testing many Premier League LWs - Mané, Sané, Martial, Son - and not being able to afford Hazard, I found SIF Lanzini. He's the best attacker by the left side you can find in Premier League for a reasonable price. Hazard is still the ideal one, but SIF Lanzini fits in perfectly. He is fast, agile, has wonderful shots and passes. His style reminds me of Insigne and Coutinho, even Hazard himself, because of the quick cut to the right foot and powerful finishing. He is a very strong game changer, but I'd only put him aside if I had a better player in the main team (which is not the case).
The pros are many. For such a good player, I thought i'd pay at least 50k on him, but his card price floats between 25k and 35k. He is a very fast player, annoying dribbler, great passer and finisher. His stamina is perfect, and you can use him all game long. The classic side-attacker.
For the cons, i'd say he is a bit weak, because of the player's stature. Very few players can be fast and strong at the same time. These ones are very expensive (Ronaldo or Pogba, for example). Obviously, he's not a very good marker.
