Manchester United are reportedly set to face competition from three Champions League clubs for the signing of Sporting striker Viktor Gyokeres.
Gyokeres is one of the most sought after strikers in world football, with his reputation having been enhanced even further by his hat-trick against Manchester City in the Champions League this week.
With Sporting boss Ruben Amorim set to take charge of United, speculation has intensified that Gyokeres could make the move to Old Trafford.
However, a deal is unlikely to be straightforward, with several other major clubs also tracking the 26-year-old.
