You're in (Luck)
I know Turkish Football, Plus I happen to know the kid personally. And I love Everton,
Here is a Detailed analysis and thoughts;
-The kid is not "Typical" Turkish Footballer. He is very much Turkish, but he has high work rate and very decent work ethic. He is got good head on his shoulders, his parents are very nice folks, Turkish Football has only been presented properly by Tugay Kerimoglu in Premiere League in recent years. Cenk Tosun may be another success, The Kid is born on June 7th, Gemini which is a good aspect for a footballer who chooses to travel abroad, as they have great flexibility and can adapt to new situations specially if they are excited about the change. Cenk Tosun is taking his chance in English Football, The team he is coming from has been playing stunning football specially in Europe in last 2 seasons. I think if Besiktas JK Performed how they performed in couple of league games this season and generally in Europe last 2 seasons, In Premiere League, and Right now They would be def in top 8 right now. Besiktas coach Senol Gunes is considered to be a Football Guru, and he really gave Tosun a lot of confidence.
His weaknesses is again His High Work Rate, what I mean by that is sometimes he tends to overdo to "Prove himself" and to Prove himself quick, so instead he needs to be very careful adjusting english gameplay and its tempo and not get muscle injury. He has a good character and a little shy with people so he needs to also warm up to his teammates in a new country, so hopefully Everton Staff will help him adjust.
Cenk Tosun's skill set is upto Everton gameplan to shine, he is good with the ball, he has improved significantly in terms of dribbling and positioning in last 2-3 seasons as he played with some experienced and talented forwards, (Mario Gomez, Vincent Aboubakar, and Demba Ba) He has learnt a lot, he was the type to stay in training late to do extra work. He needs Good Crosses most of the time but he can create space for others as well which is something he learnt to do more recently, He doesn't have one aspect of his skill test that is 9 or 10 (out of 10) it is more like 7's some 7.5's but he has got overall complete striker character. He is DEFINITELY FASTER than Giroud & If he adjusts well He will be much better striker than the Frenchman.
He needs to stay fit, focus on football only and he needs to get some good impactful first games without injury to show himself and increase his confidence right off the bat. That would really ignite his form. Hopefully Sam is going to understand the kid well and play him in attacking formations that works for the team and for Tosun. I do think He can be a great partner to Rooney, and I hope Rooney welcomes his partnership, He can learn a lot from Rooney.
Again I know the kid from interviews (being in press over in Turkey) he is a good kid. He will understand the value of playing for a very respected club in England, he just needs a little bit of Good Luck in the beginning to get his stride in if you know what I mean.
Best of Luck!
