Arsenal midfielder Mesut Ozil has signed a new three-and-a-half-year deal to stay at the club until 2021.
Ozil, 29, becomes the highest-paid player in the club's history - earning about £350,000 a week before tax.
The deal, signed on Wednesday, follows months of speculation about the future of the Germany international, whose previous contract was due to expire at the end of the season.
He joined the Gunners from Real Madrid in 2013 for a then club record £42.4m.
Ozil could have left Arsenal as a free agent in the summer and had been able to discuss a move with foreign clubs since 1 January.
The playmaker has made 21 appearances this term, scoring four goals and recording six assists, and his new deal commits him to the Premier League club until he is 32.

It comes on the day Arsenal broke their transfer record to sign striker Pierre-Emerick Aubameyang from Borussia Dortmund and follows the departure of forward Alexis Sanchez, who joined Manchester United after lengthy contract negotiations with the Gunners.
Ozil has won three FA Cups in his three-and-a-half-year spell at Emirates Stadium - and no other player has recorded more assists or created more chances in the Premier League since his debut in September 2013.
He also has 88 caps for Germany and won the 2014 World Cup.
Ozil's Arsenal career so far
Ozil joined Arsenal at the end of the 2013 summer transfer window and won the FA Cup in his first season as the club ended a nine-year wait for a trophy.
He made 32 appearances in the 2014-15 season, despite missing three months with a knee injury, and won the FA Cup for a second year in a row.
Ozil set a new Premier League record in November 2015 by becoming the first player to create a goal in six consecutive matches.
He scored nine goals and made 20 assists in the 2015-16 season and was named Arsenal's player of the season.
In 2017, Ozil won the FA Cup for the third time as Arsenal beat Chelsea at Wembley.
