The 19-year-old player has earned enthusiastic reviews for his performances for the Istanbul-based club, who rounded up in the second position in the Turkish Super Lig this season.
Under has been labeled the ‘Turkish Dybala’ because of his physical likeness and playing similarities with the Juventus player.
And it appears to be that Juventus are ready to pair the duo up, with the Serie A champions having implanted a bid for Under, according to Turkish outlet Fotomac.
By contrast, the player has told beIN Turkey that he desires a move to either Chelsea or Manchester United, with two other European big teams also in his sights.
“The league I really want to play in is the Premier League and I would also love La Liga,” Under said.
“I want to play for Manchester United or Chelsea, also Barcelona or Real Madrid.”
On the other hand, while the Premier League are yet to make a move, Basaksehir manager Abdullah Avci did confirm that Lille had also made a bid for the wonderkid.
Avci told TRT Spor: “Yes, it’s true there is some interest for Cengiz. It’s normal because the kid is a good footballer.
“I can confirm we have received only one bid for Cengiz which was came from Lille. The offer was €6.5m and we rejected it. Do we sell him, it remains to be seen, but I want him to stay with us next season.”
The 'Turkish Dybala' enjoyed an impressive breakthrough season in the Super Lig, netting nine goals and seven assists for the surprise runners-up.
