David Beckham puts Manchester United on notice following abysmal season, player incidents

But since the glory days of Beckham, Wayne Rooney and Cristiano Ronaldo, Manchester United has been mid-table at best. The Red Devils haven't finished first in the Premier League since the 2012-13 season and were second twice.

For Beckham, it has underscored the lack of success for the club. Manchester United finished this past season 15th in the table.

"We understood what it meant to play for Manchester United. We understood what the badge meant. Everywhere we traveled, whether in Europe or Asia, we respected the fans. We respected the fact that they came and paid money to see us, to get an autograph or to take pictures. You have to respect that."

Manchester United's 15th-place finish was the worst since the 1989-90 season when the club was 13th in the Premier League. The club still managed to win the FA Cup that year. But it was three more seasons until they returned to the top of the Premier League standings.
