Chelsea opened up an eight-point gap at the top of the Premier League on Sunday, with the returning Diego Costa on the scoresheet in a 2-0 win over Hull City at Stamford Bridge.
The striker, who was dropped from the squad for the match with Leicester City last weekend amid reports of a row with manager Antonio Conte, grabbed his 15th goal of the season in first-half stoppage time. Meanwhile, Gary Cahill headed in a second 10 minutes from time to make the match safe.
Earlier in the day, Arsenal’s Alexis Sanchez scored a 98th-minute penalty to see his side to a dramatic 2-1 win over Burnley and second place in the table.
