Tottenham Hotspur academy coach Bradley Allen has admitted his surprise at the first team’s victory over Chelsea on New Year’s Day.
Spurs came from a goal down to get the better of their London rivals 5-3 at White Hart Lane in the Premier League on Thursday.
Diego Costa put Chelsea ahead in the 18th minute, but Tottenham equalised through Harry Kane on the half-hour mark and Danny Rose made it 2-1 on 44 minutes.
Mauricio Pochettino’s side went into the half-time interval 3-1 up after Andros Townsend slotted home the penalty conceded by Gary Cahill, while Kane scored Spurs’ fourth goal of the match seven minutes into the second half.
Eden Hazard threatened a comeback for Chelsea on the hour mark when he pulled one back, but Nacer Chadli ended the game as a contest on 78 minutes when he made it 5-2 to Tottenham.
John Terry scored three minutes from full time for the Blues, but it did not matter in the end as Spurs won the match 5-3.
Allen conceded his surprise at Tottenham’s win and told BBC Sport on Thursday: “Tottenham showed everybody tonight how to play against Chelsea.
“I think Chelsea can justifiably say they've played a lot of games in recent weeks, and it caught up with them. This was a free hit for Tottenham tonight.
"The game turned when Harry Kane equalised. Spurs thought: 'If we can keep going at this Chelsea defence, it could be our night.' I never thought I'd see this result in a million years.”
Tottenham are currently fifth in the Premier League table with 34 points from 20 matches, just two points behind fourth-placed Southampton.
