Newcastle United are among the clubs that will travel to Istanbul this weekend to scout a Crystal Palace player, according to Fotospor.
Newcastle, along with AS Monaco and Brighton & Hove Albion, are said to be 'closely interested' in the loaned-out Palace striker Alexander Sörloth, who has already been linked with a move to Aston Villa.
Sörloth has scored or assisted 28 goals in 33 games for Trabzonspor this season - 18 more than he managed in 20 Eagles appearances.
It is claimed that Trabzonspor, who face Besiktas on Saturday, have a clause to turn the Norwegian's two-year loan deal permanent this summer.
And it remains to be seen how Newcastle's interest would affect that.
It is unclear how much Sörloth would cost the Turkish side, though Palace are reported to have paid £8.1 million to sign him from FC Midtjylland in January 2018.
