Both players were short of full fitness for Saturday's Premier League clash with Leeds, and thus missed out on selection.
The boss admitted that he was unsure if the pair would return in time for Wednesday’s Champions League showdown away to Dortmund, but revealed a verdict would likely be reached at some point on Monday.
“On Monday we will know it.”
It was a frustrating day at the office in Saturday's clash with Leeds, with Stuart Dallas snatching all three points in stoppage time for the visitors.
Opposition midfielder Raphinha was highlighted for particular praise following the result and Guardiola agreed that, while City dominated, the Brazilian made a significant impact.
“Yes, he ran two times, no more than that," the boss reflected.
“Of course he is a weapon. He is an exceptional player with good pace.
“Every player under Marcelo is getting better and he played a good game.”
