Barcelona are at the front of the queue to sign Eintracht Frankfurt striker Luka Jovic this summer amid interest from a host of other European clubs.
Goal understands Real Madrid, Chelsea and Bayern Munich are all monitoring the Serbia international's progress, with the 21-year-old having scored 19 goals in 29 appearances this season.
Frankfurt are hopeful of completing the permanent signing of the Benfica loanee this summer for €6 million (£5.3m/$6.8m) and are set to demand around €60m (£52m/$68m) for his signature.
