United could not qualify for the Champions League and are currently playing in the Europa League.
After finishing fifth in the last Premier League campaign, Manchester United could not qualify for the Champions League and are currently playing in the Europa League, the second-tier competition in Europe.
Manchester United have played three fewer home games compared to a year ago due to the scheduling of Premier League fixtures and their matchday revenue has taken a hit because of that.
"Our financial results for this quarter reflect the impact of our non-participation in the UEFA Champions League, we are pleased that we remain on track to deliver record revenues for the coming year," United Executive Vice-Chairman Ed Woodward said in a statement.
United earned £31.2m for three months to September 30 before interest, tax, depreciation and amortisation a fall from a record £41.6m earned a year earlier.
Revenue came in at £120.2m from £123.6M a year ago but commercial revenue rose 4.4% to £74.3M and now makes up about 62% the club announced.
Manchester United have the same profit forecasts for the 2016-17 year as a whole.
