Breaking news : As Ralf Ragnick identifies long lost Manchester United player as he is set to start game against Middlesbrough

 Manchester United are set to return 

to action after a 13-day break since

 their last match.

Middlesbrough stand between Ralf 

Rangnick’s side and a place in the fifth

 round of the FA Cup on Friday night.

Rangnick has conducted his pre-match

 press conference on United’s official 

app at 2pm, and was asked what he 

expects from his full-backs.

The German gave some tactical detail

 and also said that Luke Shaw is likely 

to come back into his starting eleven 

after a period absent with injury.

“The full-backs have to be both defenders 

and at the same time give as much input

 as the possibly can if we’re in possession

,” said Rangnick.

“They have to be offensive defenders 

and I think in the last couple of weeks 

we have improved in those areas. It 

will also be an important position in 

tomorrow’s game because Middlesbrough

 will play with a back five with very 

offensive wing-backs at times.

“It will be very important that our 

own full backs are on a very high tactical

 level. Also, I am happy with the development

 of the players in those positions.

“Luke will be back and he will probably

 play from the beginning because Alex 

Telles only came back last night and 

played for Brazil for 90 minutes. This

 is what I want to see – offensive 

full backs playing almost like wingers 

but also being modern defenders, 

winning duels.”

Telles and Diogo Dalot have established

 themselves as first choice under Rangnick

, although Shaw and Aaron Wan-

Bissaka have been missing lately.

Shaw may well get a chance to remind

 his manager what he can do here, given

 his most recent appearance was almost

 a month ago in the third round win 

over Aston Villa.

As Rangnick said, Boro’s wing back 

system could cause a tactical conundrum

 for Shaw, especially if he shows any 

signs of rustiness after his spell on 

the sidelines.

The England international has not 

been at his best this season, perhaps 

suffering a hangover from his European

 Championship excursions in the summer

, and he will be looking to get his 

campaign back on track, starting tomorrow.
