Aston Villa ran out winners over Derby County in the play-off final, as they made it to the Premier League.
Tomori and Abraham have been in Chelsea’s youth system since they were children and know each other really well.
However, on the final day of last season they were up against each other, with Tomori playing for Derby and Abraham representing Villa.
The walk down the tunnel on Championship play off final day can be very nerve wracking.
But Tomori admits that as soon as he saw Abraham in a Villa shirt he almost burst out laughing.
“The play-off final last season was tough,” he admitted.
“I remember in the tunnel before the game, they were out already before us, I walked out and I’ve seen him and I knew if I looked at him for too long I was going to laugh. I knew I had to be serious.
“He was playing up front and I’m defending, so we were next to each other the whole game and didn’t say a word to each other, nothing.
“It was serious but strange. I’m happy for him that they won, but was also disappointed because it was such a good year for us.”
Both Tomori and Abraham had stand out loan spells at Derby and Villa respectively.
The pair have now returned to Chelsea and are making an impact on the biggest stage.
Tomori and Abraham have both played key roles in Frank Lampard’s starting line-up this season, and their form has earned them call-ups to England’s senior side.
England are set to take on the Czech Republic and Bulgaria in the coming days, with the young Chelsea duo both hoping to receive some game time.
