Manchester City assistant manager Juanma Lilo said Pep Guardiola is in continuous contact as he recuperates from back surgery in Barcelona.
Lilo recently returned to City for a second spell alongside Guardiola either side of a short stint in charge of Qatari club Al Sadd.
The 57-year-old will be in charge on matchday for the English champions at Bramall Lane but said Guardiola is still taking a full part in preparing for the match.
"Pep is always there! The contact is continuous. Telephone, video call, everything," Lilo said at City's pre-match press conference on Friday.
“He is watching Sheffield United right now. What’s important is his health. That's what matters.
"That doesn't keep him from being who he is. He’s fully focused on the team and the match."
