Manchester United signed Morocco's Sofyan Amrabat on loan as part of three arrivals at Old Trafford in the hectic final hours before Friday's transfer deadline, while Liverpool reportedly turned down a £150 million ($190 million) offer from Saudi Arabia for Mohamed Salah.

United waited late to get a deal done for midfielder Amrabat that will see one of the stars of Morocco's run to the World Cup semi-finals join from Fiorentina for a 10 million euro (£8.6 million) loan fee with the option to buy for a further 25 million euros next year.

Amrabat was joined by Turkish goalkeeper Altay Bayindir from Fenerbahce and Spanish left-back Sergio Reguilon, who was with Spurs.

"It is a huge honour to become a Manchester United player. I’ve had to be patient for this moment but I’m someone who always listens to my heart and now I am representing the club of my dreams," expressed Amrabat in a United statement.

Mason Greenwood departed United on Friday, joining Spanish side Getafe on loan. The club and Greenwood mutually agreed for the forward to continue his career elsewhere after he faced allegations of abuse involving a young woman.

On their part, Liverpool completed their midfield overhaul with the signing of Ryan Gravenberch from Bayern Munich in a £35 million deal.

But the club stood firm in the face of Al-Ittihad's attempt to tempt Salah to the Saudi Pro League.

"The position remains the same. Absolutely no doubt about that," Liverpool boss Jurgen Klopp said of the club's desire to keep the 31-year-old, who has two years left to run on his contract.

However, the Saudi transfer window does not close until September 7.

Brighton also surprised observers by signing Spanish international winger Ansu Fati on a season-long loan deal from Barcelona.

Four years ago, Fati was regarded as one of the most promising talents in Europe, before injuries halted his progress.

"This is a great deal for all of us. I am sure Ansu will help us to reach a new target and we can help him get back to the level he deserves to be," Brighton boss Roberto De Zerbi said.

English top-flight clubs smashed their record for spending on new players during this window, with the total surpassing £2 billion for the first time, according to financial experts Deloitte.

"You've got that intensity of competition across the league. Whether that's competing for the title, competing for European places or just simply staying in the league, that's driving spending," indicated Calum Ross, assistant director in Deloitte's Sports Business Group.

"There are 10 clubs that have spent more than £100 million."
