Dele Alli has signed a six-year contract extension with Tottenham Hotspur through 2024.

Alli will have an increase in salary as part of the deal.

Alli joined Spurs in a £5 million deal from MK Dons in 2015.

Marcos Alonso has signed an extension with Chelsea through 2023.

"I am so happy to stay here longer and to keep playing for one of the best teams in the world," Alonso told Chelsea's website. "It's been a very good two seasons and I am looking forward to more."

Alonso was a relatively unheralded signing for Chelsea, in a £24 million deal from Fiorentina, in August 2016 but has established himself as a key contributor, operating effectively at left wing-back under Antonio Conte and transitioning well to the left of a back four since Maurizio Sarri's arrival.

Luke Shaw has signed a new five-year extension to remain with Manchester United until June 2023.

Shaw's existing deal was due to expire next summer after United triggered a one-year extension at the end of last season.

"Since I came to United it's been a whirlwind four years that have passed so quickly," he said. "I am very proud to sign my new contract and continue my stay at this great club.

"I want to thank everybody that has stood by me and shown me huge support - the management, my team-mates and the fans. I want to let everyone know that I will give everything I have to repay them and deliver success over the years to come. I'm still very young with a lot more to learn and I can't wait to continue my progress under Jose Mourinho."

Shaw has been given a significant increase on his £100,000-a-week wages after becoming Jose Mourinho's first choice left-back this season.
