Manchester United's plans to participate in the 2014 International Champions Cup this summer could impact on their potential Europa League campaign should they qualify for the competition, according to the Guardian.
The Red Devils plan to tour the United States this summer as part of their pre-season and will participate in the tournament alongside Manchester City, Liverpool, Real Madrid, Internazionale, Milan, Roma and Olympiakos.
The dates of their tour are yet to be confirmed but the Guardian reports that Manchester United are due to fly out three weeks after the World Cup in Brazil concludes on July 13.
However that could become an issue if they qualify for the Europa League.
As it stands Manchester United occupy 7th place in the Premier League which means they would qualify for European club football's second-tier competition - depending on who wins the FA Cup and the League Cup.
If the do qualify for the competition, the Red Devils would have to start their campaign in late July, which would clash with their pre-season plans.
A spokesman for Manchester United said: There is a long way to go, 42 points to play for, so it is issue we'll address at the time, if required to do so."
Manchester United will play their first fixture of the International Champions Cup against Roma on July 26.
Richard Arnold, managing director, said: "I'm delighted to announce that the team will be returning to the USA for our 2014 Tour.
"Since the club's last visit in 2011, the appeal of football in America has grown rapidly.
"NBC reported that this season's Premier League opening weekend saw the average viewership rise by 78% from the 2012-13 season, with Manchester United's match against Swansea being the most-watched game.
"Manchester United has over eight million followers in the United States."
