Manchester United manager Jose Mourinho on Thursday hailed new signing Alexis Sanchez as one of the “best attacking players in the world”, confirming he will be in the squad to face Yeovil in the FA Cup.

United travel to the fourth-tier club on Friday at the start of a weekend that will also see Premier League leaders Manchester City tested by Championship high-fliers Cardiff and Liverpool taking on West Brom in the fourth round.

Chile international Sanchez, 29, completed his transfer from Arsenal on Monday in a straight swap deal that saw Henrikh Mkhitaryan move in the opposite direction.

Sanchez is available for the Huish Park tie because he did not appear for Arsenal in their third-round loss at Nottingham Forest.

“We’ve got one of the best attacking players in the world. I think he’ll be very important for us because we want to have the best players possible,” Mourinho told reporters.

“Alexis is a player that becomes more than a player because of his multi-functionality,” he added. “I say he can play in four different positions in attack.”

Earlier this week Yeovil, playing United in the FA Cup for the second time in four seasons, reacted to Sanchez’s potential debut on their home ground.

Mourinho was asked about the possibility of another big acquisition, the return of Real Madrid superstar Cristiano Ronaldo to Old Trafford.

“Madrid is on fire, the results are not good,” said the United boss. “I care about the club. I am the last one to add fire. Cristiano is the kind of player that every manager and club wants but only one manager and club can have him, (Zinedine) Zidane and Real Madrid.”
