Manchester United have no recall clause in Alexis Sanchez's deal at Inter Milan.
The Mirror says United cannot recall Sanchez from his loan spell at Inter Milan to solve their striker crisis.
United's leading goalscorer Marcus Rashford is out for up to three months with a double stress fracture of the back.
That has left United boss Ole Gunnar Solskjaer with Anthony Martial and 18-year-old Mason Greenwood as his only options up front.
United are exploring short-term deals for strikers to fill the void left by Rashford's enforced lay-off.
But it has emerged there is no chance of recalling Sanchez from his season-long spell at Inter, because no recall clause was inserted in the agreement with the Italian club.
