Manchester United are exploring the prospect of signing Benfica star Goncalo Ramos.

Ramos is understood to be disappointed that Benfica's board have not yet rewarded him for his efforts with a new and improved contract.

Benfica president Rui Costa promised the striker a pay-rise before the start of the season - which has yet to materialise.

The Portugal international striker's contract runs to June 2026, but he is growing increasingly frustrated with his current situation, says The Sun.

If the 21-year-old does decide to leave Lisbon in the summer, any potential suitors - including United - would have to trigger his huge £105.6million release clause.
