"We are looking forward to the season starting now, with a hard game against Huddersfield", Sarri said.
Wolves, Championship winners and heavy spenders during the summer, had more luck in their initial game after battling Everton to a 2-2 draw. "We thought he would manage maximum 60 minutes and he went much longer", said Mourinho.
Other major European leagues have the rest of the month to complete their business, which is part of the reason why United voted against an early end to the Premier League window.

Jurgen Klopp's Liverpool did reach they Champions League final, which they lost to Real Madrid, while the Premier League's other biggest clubs, Chelsea and Arsenal, disappointed and missed out on the top four.
"If you have a build-up of anticipation and atmosphere you can psychologically get in referees' heads".
"If you can't add a player that can improve your squad, the most important thing is to make sure you do not lose your best players and I think that was a great job from the club to keep the best players and the manager".
