Arsenal head into the World Cup break five points clear at the top of the Premier League after they beat the Wolves 2-0 on Saturday as Manchester City suffered a shock 2-1 home defeat to Brentford.
Newcastle remains third after inflicting Chelsea's third consecutive league defeat 1-0 at St. James' Park, while Tottenham scored twice in the final 10 minutes to win a 4-3 thriller against Leeds.

A lackluster City performance was punished in the eighth minute of time added on when Brentford cut open Guardiola's men on the counterattack and Toney tapped in Josh Dasilva's cross.
"The better team won," conceded Guardiola. "We had a lot of problems and we could not press as they didn't allow us."
Thomas Frank hailed the result as perhaps Brentford's best ever as they moved up to 10th in the Premier League.
"Speaking to some people from the club, this is probably the single biggest ever result," said Frank. "Against one of the richest clubs in the world and we have one of the lowest budgets in the division."
