If Goldman Sachs CEO Lloyd Blankfein looked sluggish on Monday, he had good reason.

Sources tell The Post that Wall Street’s highest profile exec was partying at the Super Bowl in Miami with other bank executives, who described Blankfein as having a good time. The revelry apparently took place a pre-Super Bowl party, sources say.

It’s not clear which team the CEO was supporting, but seeing as how everything that Goldman touches turns to gold, one has to assume that it was the New Orleans Saints, who beat the Indianopolis Colts 31-17 off a Peyton Mannning interception in the waning minutes of the fourth quarter.
