Kai Havertz scored the late winner as big-spending Chelsea fought back for a controversial 2-1 win against West Ham, while Liverpool boss Jurgen Klopp praised Everton keeper Jordan Pickford's "spectacular" display in Saturday's goalless Merseyside derby.
Having embarked on a 250 million pound ($280 million) spending spree in the summer transfer window, Chelsea are expected to deliver on their new owners' eye-watering investment.
The early returns had been mixed as Chelsea crashed to defeats against Leeds and Southampton. So when Michail Antonio gave West Ham a shock 62nd minute lead with a close-range finish, the critics were sharpening their knives at Stamford Bridge.
But Ben Chilwell equalised in the 76th minute, just three minutes after the England left-back replaced Marc Cucurella. Chilwell headed Thiago Silva's lofted ball past his marker, spun around and poked his shot through Lukasz Fabianski's legs from a tight angle.
