According to Turkish sources it looks like Everton maybe trying to add some attacking options by signing Kerim Frei of Besiktas of the Turkish Super Lig. He has some British experience playing for Fulham where he totaled 23 appearances in the Premier League with the Cottagers after spending time at their academy and on loan at Cardiff.
He is only 22 years old and has played 2 seasons in Besiktas since joining them in September of 2013. He is a strong passer with a 86% completion rate last season, but overall seems like a potential bench player for Everton. He scored 5 goals in 37 appearances for his side in all competitions at an attacking left wing position. He mainly plays a left wing and unless moved that leaves him facing Kevin Mirallas for playing time. Still, it’s better than seeing Tom Cleverley or Arouna Kone shifted wide left.
His strengths are dribbling, passing and through balls, but is weak on crosses and defense. That says to me right there he is just a younger Mirallas and until he faces the Premier League again I’m not even sure how close he is. His cost is estimated around £6 million so wouldn’t hurt the transfer budget Ronald Koeman has gotten, but I also wouldn’t think this is the big splash Everton is looking to make either.
