The race for the coveted trophy switched into Manchester City's hands when the Reds suffered a 2-0 loss to Chelsea at Anfield last Sunday.
City have three games left to play while Liverpool, who are league leaders, have just two, which could result in the champions being decided on goal difference on May 11.
"I'm still upset [about losing to Chelsea]," Suarez told Uruguayan TV channel Canal 10. "It was so frustrating. We couldn't find spaces, we made a mistake and it was hard to deal with.
"We knew the game was going to be hard and tight. We all got nervous and lost control. We are hoping Man City lose some points but in the Premier League you never know - anything is possible."
City will take on Everton this Saturday, while Liverpool will play Crystal Palace at Selhurst Park on Monday.
