Manchester Untied could lose two goalkeepers as a result of David De Gea's contract renewal.
The Spaniard has committed to a long term deal that could see him stay at the club until 2023.
It would see De Gea complete more than 10 years at United, a club he was always expected to leave in his prime.
Romero is currently De Gea's backup, while Henderson is on loan at Sheffield United.
The latter is certain to want a chance to start at United, or he may see his career best served at another club.
