Leeds United are tracking Besiktas winger Jeremain Lens, according to Turkish media outlet Fotomac.
Leeds scouts were present to watch the former Sunderland player in action for the Black Eagles in their 3-2 win over Sarpsborg in the Europa League on Thursday night.
The Netherlands international caught the attention of the United representatives present as Besiktas came from two goals behind to produce a spectacular comeback.
Lens has been impressing in Turkey since joining the SuperLig side in August 2017 and has scored five times in 18 appearances in all competitions so far this season.
Leeds are understood to be preparing to make a bid when the January transfer window opens as Marcelo Bielsa looks to maintain their promotion push for the Premier League but Besiktas are likely to dig in their heels with the 31-year-old under contract with the club until the summer of 2022.
Lens is no stranger to English football having had a three-year spell with Sunderland where he scored four times in 24 appearances.
Brought to Wearside by Dick Advocaat in July 2015, it began well with two goals and two assists in his first eight matches but once Sam Allardyce replaced Advocaat three months later, the winger fell out of favour.
Things got worse when Lens refused to take part in a warm-down following a defeat to Watford in December and he was dropped from the squad as well as being fined two-weeks wages.
He was shipped out to Fenerbache and Besiktas on loan over the next two years before joining the latter on a permanent deal earlier this year with the Black Eagles reported to have paid around £6million for his services.
Pablo Hernandez’s goal was enough to give Leeds the three points in their Yorkshire derby with Sheffield United on Saturday.
That was their third straight victory in a row and keeps the Whites in the race for automatic promotion and are just a point off leaders Norwich City.
Leeds host Queens Park Rangers at Elland Road on Saturday before an away trip to Bolton Wanderers seven days later.
