Peterborough's hopes of a quick return to The Championship were dashed last night, with defeat in their League One play-off semi-final.
Peterborough Utd chairman Darragh MacAnthony said that he was disappointed by the attendance at London Road for the win over Colchester.
Peterborough United manager Darren Ferguson has praised his side's "clinical" finishing after Posh beat Chesterfield 3-1 at Wembley.
Olympic Way is a sea of blue and white as Peterborough United and Chesterfield fans head to Wembley Stadium for the Johnstone's Paints Trophy Final.
It's Posh's third visit to Wembley. They've won on their previous two trips in 1992 and 2000.
Peterborough United midfielder Danny Kearns has joined League Two leaders Chesterfield on a month's loan.
Posh take on The Spireites in the final of the Johnstone's Paint Trophy later this month, but Kearns won't be able to feature having already played for Peterborough earlier in the competition.
22-year-old Kearns has previously enjoyed loan spells at York City and Rotherham United during his time at London Road.
Posh are on the crest of a wave having secured their place in the final of the Johnstone's Paint Trophy this week, but Ferguson says his players mustn't be complacent against Boro.
"Stevenage play a particular way, they've got high energy and we're going to have to match that," Ferguson told ITV News Anglia.
"When we get the ball, we're going to have to play good football - that will be the key. It's always a difficult game at Stevenage and I don't expect anything different on Saturday."
Posh will take on Chesterfield in the JPT final at the end of March, but Washington believes that his team could return a couple of months later in the League One play-off final.
"Obviously, the place is buzzing with the lads getting to Wembley," Washington told ITV News Anglia.
"Everyone's really excited and it's a great opportunity for all the lads. Now we've got to fight hard for the rest of the season to hopefully get there again."
Peterborough travel to local rivals Stevenage on Saturday in a game which carries huge significance at both ends of the table.
