The 23-year-old has been a standout performer for the League One side of late, and finished the season with 12 goals and 11 assists across 31 outings in all competitions as the Posh slumped to an 18th-place finish in the third tier.

The final against Sheffield United was incredibly eventful as Sunderland conceded the first goal of the game played at Wembley as Tyrese Campbell scored the opening goal of the final, before Sunderland made the comeback in the second half.

And the game — and at least £200million ($270m) — was secured when 19-year-old Watson kept his cool to slip in the winning goal in the 95th minute. Watson came through the Sunderland academy but a deal was agreed in April for him to join Brighton this summer. Here, Philip Buckingham and Tim Spiers break down the game.
