Third parties held talks with representatives from Old Trafford and Chelsea in London last week, with the Premier League duo going head-to-head to sign the highly-rated youngster.
Manchester United is leading Chelsea in the race to sign Anderlecht teenager Youri Tielemans, according to a source.
Goal UK understands that third party discussions were held in London last week with representatives from both clubs over possible moves for Tielemans next summer.
The 18-year-old midfielder is already one of the most sought-after youngsters in European football despite only leaving school last year.
