Thomas Tuchel's alterations in the second half on Saturday made a defining difference against West Ham United. Two of his five substitutes got on the scoresheet to complete a dramatic second-half comeback after falling behind to Antonio's opening goal.
Ben Chilwell proved the defining influence, making a decisive run and finish to net the equaliser before setting up Kai Havertz winner in the 88th minute. Armando Broja also offered a different dimension that unsettled West Ham's defence, who endured a painless afternoon until the Albanian's arrival, finding it easy to nullify the shorter attacking pair of Raheem Sterling and Christian Pulisic.
Mason Mount's usual burst of energy was apparent, as was his attempts to connect with a more obvious focal point in Broja. The only blot in Tuchel's changes was the final one in Jorginho, whose complacency near his own box almost cost Chelsea before Havertz winner, losing possession that led to Maxwell Cornet heading the ball off Edouard Mendy's post from close range.
