Unai Emery delivered an overdue update on Danny Welbeck, the Arsenal striker who was stricken against Sporting in the Europa League last Thursday. Welbeck, the manager reported, underwent surgery last Friday to repair his badly broken ankle and he will be out for some time. With Welbeck’s contract due to expire at the end of the season, has he played his final game for the club? Emery had more pressing matters with his strikers against Wolves and he made a tactical change at half‑time, switching from 4-2-3-1 to 4-3-1-2 in order to allow Pierre-Emerick Aubameyang to come in from the flank and partner Alexandre Lacazette up front. In the first half, Aubameyang had routinely drifted inside from the left. He did not look comfortable in that role. Arsenal would improve to draw 1-1. Is it the best use of Aubameyang’s talents to play him off the wing? David Hytner

Cardiff have made a miserable start to the season, and are second favourites to go down. Yet, after Brighton lost against them, Chris Hughton decided that what he really needed to do was criticise the officials. The reality is, the laws of football are badly drafted and interpreting them requires officials to perform tasks beyond the capability of the human eye. Big mistakes are inevitable. So though Sol Bamba was, as Hughton says, offside before scoring the winning goal, that is not the point. What is the point is that Brighton took an early lead, missed fine chances to extend it and then, after Cardiff equalised, Dale Stephens got himself sent off. Which is to say that Brighton lost not because the officials made mistakes but because Brighton made mistakes. Hughton and his players would do well to acknowledge that. Daniel Harris

Marco Silva was asked about Everton’s shackling of Eden Hazard in the wake of Chelsea’s first scoreless display at Stamford Bridge under Maurizio Sarri. While he acknowledged the Belgian as the Premier League’s player of the season to date, he pointed to another tactic which had paid off handsomely to blunt the home side’s intent: Gylfi Sigurdsson and Richarlison had been charged with closing down Jorginho and unsettling “one of the keys in Maurizio’s system”. The Italy midfielder was hassled out of possession too often and unable to dictate the pace of Chelsea’s approach before being hauled off just after the hour. “He controls the match with the ball for Chelsea, but we blocked him fantastically,” the Everton manager said, offering others an insight into how to frustrate this team’s ambition.

What had happened to Hugo Lloris? An hour into this match the Spurs goalkeeper became a clear target for the Crystal Palace artillery after the Frenchman had punched one cross on to the head of Palace’s James Tomkins, only for the ball to skid wide, and flapped at others. The next corner was worse, Lloris staying rooted to his line and giving Tomkins a free header that he put wide. It’s been a strange season on the pitch for Lloris and a problematic one off it. But Mauricio Pochettino has stuck with his man and in the last minute Lloris showed why, blocking Alexander Sørloth’s close-range shot with a superbly agile save to preserve a win for Spurs. “The players are not machines and can have ups and downs,” said Pochettino, “but I am super supportive with the players. Hugo is one of the best there is, no doubt.” Paul MacInnes
