Pep Guardiola jokes he is a 'genius' after substitutes lead Man City to victory

Pep Guardiola joked he was “a genius” after a double substitution kept Manchester City on Arsenal’s tail in the Premier League title race. Riyad Mahrez fired City to a 1-0 win at Chelsea to cut the deficit to the leaders back to five points. Less than three minutes after coming on as substitutes, Jack Grealish teed up Mahrez for the winner which keeps Arsenal firmly in their sights.
