Jorginho's stoppage-time penalty ensured Chelsea avoided conceding further ground in the Premier League title race with a dramatic victory over Leeds United at Stamford Bridge.
Teenager Joe Gelhardt, brought on as an 81st-minute substitute, appeared to have earned a late point for Leeds with his first touch - the 19-year-old sliding in to send Tyler Roberts' low cross past Edouard Mendy.
In a hugely entertaining encounter featuring three converted penalties, Raphinha put the visitors ahead with the game's first spot-kick after 28 minutes following Marcos Alonso's mistimed challenge on Daniel James.
But Chelsea, knocked off top spot in the table following their 3-2 defeat by West Ham last weekend, fought back as Mason Mount met Alonso's low cross with a first-time finish to restore parity before the interval.
