Chelsea's youth team beat Arsenal 3-1 on Tuesday lunchtime to leapfrog their London rivals at the top of the Under-18 Premier League and put themselves on the brink of an historic Treble.
Having already secured the southern section of the Under-18 Premier League and another FA Youth Cup, Jody Morris's side have now moved a step closer to the national championship as well.
Goals from Cole Dasilva, Trevoh Chalobah and Martell Taylor-Crossdale at Cobham mean the young Blues, like Antonio Conte's first-team, will be crowned champions if they win on Friday.
While the seniors head to West Brom in their bid to get over the finishing line, Morris's under-18 side are at home to Reading in their title decider.
