Brazilian winger Savinho was forced to come off in the closing stages of the 2-1 win over the Bees with what initially looked a muscle problem.
Though the boss admitted he hadn’t confirmed as much with the Club doctor, he says he is hopeful it isn’t a major issue.
“It looks like cramp,” said Pep. “I didn’t speak to the doctor; we will see.”
And the Catalan also had encouraging news on Phil Foden, who has missed the past three games with illness.
Now, according to Guardiola, the England star is closing on a City return.
“He didn’t train too many sessions,” he said.
“Step by step. I am delighted he is back. We need him desperately and it’s important for us that he is back.
“He has trained this week. The game was tight, and I decided to use other options.”
The Spaniard had an exhausting last season for club and country and was given an extended break before returning to training and now appears to be rested and ready to go again,
“He came on and played really well,” said Pep.
“He has been injured, played a few minutes for the national team and today played his first 45 for us.
“He said he felt good. Rodri is so important for us. Kova has been amazing, and Rodri cannot play all the minutes, so we rotate.
“We need that. It was important that Gundo had extra minute and Kyle had his first minutes, John (Stones), too.”
