The Liverpool striker has scored 30 goals as the club has charged to the top of the table and he believes even the players have been taken back by their success this season.
Brendan Rodgers' side has been in superlative form in the second half of the season, currently enjoying an 11-match winning streak in the league - a club record.
Seven points from the remaining three fixtures - against Chelsea, Crystal Palace and Newcastle United - will see the club win the title for the first time since the Premier League's inception.
"It (winning the title) would be something that no one would believe," the Uruguayan told Perform. "Because we have good players but if you look at the complete roster, we don't have (players) to be up there. The truth is that we are surprised ourselves at how well we're playing.
"We have good players who are demonstrating why they are in Liverpool and it would be something amazing even to England because of the investment made by Chelsea, (Manchester) City and Arsenal.
"Even Tottenham have spent over 100 million pounds and we, with so little investment, are in that position. It would be incredible."
Suarez pinpointed February's last-gasp 3-2 win over Fulham, sealed by a Steven Gerrard penalty as the game which gave Liverpool the belief that the team could be a serious title contender.
"I think that as we were playing, we were starting to realize that we could be at the top [of the table]," he said.
"We never had aspirations to be champions, but I think the game against Fulham, that we won in injury time with a penalty by Stevie was a reflection that we can be on top and that with character we can bring up results."
