Manchester United are said to be keeping tabs on young goalkeeper Djordje Petrovic.
The Red Devils are vying for Inter Milan star Andre Onana in a blockbuster summer deal.
While Onana is their main target to replace David De Gea, the Manchester Evening News claims that Petrovic is also on their radar.
United see him as one of the future, with the 23-year-old impressing in MLS with New England Revolution.
There is the possibility United sign two keepers this summer, especially if De Gea and Dean Henderson both leave.
The latter wants a move to Nottingham Forest, while De Gea is presently out of contract.
