Yes, I'd be happy too!
Jahanbakhsh is a pure winger in regards to the many types of wingers we see play in modern times. As of today, he has become the top scorer of the Eredivise finishing at 21 goals and he is second best in assists finishing at 12 assists for this season. (In 32 games) Jahanbakhsh becomes the first Asian player in history to finish as the Top Scorer in a top flight European league. Some of his stats: 21 goals, 12 assists, 78 key passes, and 112 successful dribbles. (One of the best dribbling stats in Europe) He is a good playmaker/assister for his team, skill moves, and amazing long shots. (He would be an amazing back up for Mahrez, but would have a huge gap to fufill). After his match today, this would be his 2nd hat-trick of the season. (If not mistaken, he broke AZ's winger record in terms of goals/assists being their current most successful winger in terms of stats) He has a lot of potential!
Some slight concerns with him would be goal conversion rate. Initially his conversion rate was poor at the beginning of the season, but has improved greatly over the course of the season. Another concern is, rarely does he track back to help defense and relies on his full back (Svensson) to do the work and in the beginning of his time at AZ he was weak on the ball, but improved in that regard as well. A final concern would be his play-style relies on possession, hence why he is more successful for AZ Alkmaar than he is for Iran (In Iran we play counter attacking football, so we don't have too much possession of the ball) and so to get the most out of his potential he would need to join a possession based team and players which are equal to or higher than him in terms of skills and experience.
Cheers, let me know if you have anymore questions!
