Both players could not continue into extra time in Wednesday’s Champions League clash with Real Madrid and were substituted.
The boss days Haaland felt a twinge and so did not risk an additional 30 minutes, while De Bruyne’s long absence with a hamstring issue this season saw his energy levels depleted after such a high intensity battle with the Spaniards.
However, neither player has been ruled out.
“Kevin is well,” said Guardiola. “Erling. we will see.
“I don’t know I’m not a doctor. He said a little bit niggles and we’ll see his evolution in the next hours.
“It was a tough game [against Madrid]. 120 mins of action. High intensity for both sides. Erling felt something. A muscular issue that meant he could not continue.
“Kevin was exhausted after five months out injured. That is normal. We will see tomorrow.
“It’s normal. The number of games this season and previous seasons, not much recovery and extra time and high intensity the way we play.
“We put a lot of pressure in our game. They are human beings, not machines and sometimes fatigue is there.”
