Mesut Ozil has announced on Twitter he has signed a new contract to keep him at Arsenal for "three more years".
There were concerns the German would follow Alexis Sanchez out of Arsenal with both players' contracts expiring in the summer.
Ozil has, however, chosen to stay which will be a big boost to Arsene Wenger and his new signings Henrikh Mkhitaryan and Pierre-Emerick Aubameyang.

Preston striker Jordan Hugill has completed his deadline-day switch to West Ham.
The 25-year-old former non-league striker has been attracting admirers with his performances since moving to Deepdale from Port Vale in 2014.
Hugill is now a Premier League player having penned a four-and-a-half-year deal at West Ham, who have paid an undisclosed fee that Preston confirm is a record sale.
"I'm absolutely delighted!" Hugill, who has been given the number 12 shirt, said.
"It's been a long day, but to get this over the line is amazing for me and it's now a new challenge for me and hopefully I can bring what I did at Preston here and show what I can do. We got on the train at lunchtime and I couldn't tell you what happened, it's all been a blur!
"It's amazing to know I'm a Premier League footballer, to know where I've come from in the last five years to where I am now in the Premier League is amazing.
"I'm still pinching myself to see if it's all real, but hopefully I can bring my qualities from Preston here to West Ham. Without a doubt it's a huge opportunity and I'm looking forward to it."
Islam Slimani has sealed a loan move to Newcastle from Leicester until the end of the season.
The striker, the Foxes' £30million record signing, joins to help the Magpies' battle against relegation.
"It's a great thing for me and for Newcastle. I'm happy to be here. Hopefully I can come here and be able to give them a hand," Slimani told the club's official website.
"Knowing the power of the fans and crowd here and how great they are, and also speaking to the manager, it gave me the confidence that this was the right choice."
Newcastle boss Rafa Benitez has been desperately chasing reinforcements with the club a point above the bottom three after Wednesday's 1-1 draw with Burnley.
He added: "Slimani is a player with experience in the Premier league, and obviously we were looking for that.
"He is a player who can fight with defenders, challenge and score goals. Hopefully he can give us some experience and some different characteristics to the strikers that we have at the moment."
The collapse of Amanda Staveley's takeover left the Magpies' transfer plans in limbo but they have managed to sign Slimani.
The Algeria international has failed to impress at the King Power Stadium since his record move in August 2016.
He has scored just 13 times - eight in the Premier League - in 46 appearances having struggled under Claudio Ranieri, Craig Shakespeare and Claude Puel.
Liverpool winger Lazar Markovic has joined Anderlecht on loan until the end of the season.
The Serbian made 34 appearances for the Reds in his first campaign after joining from Benfica for £20million in July 2014, but he has been deemed surplus to requirements under Jurgen Klopp.
Markovic has had loan spells with Fenerbahce, Sporting Lisbon and Hull, and the Merseyside club announced on their website that the 23-year-old is on the move again.
"Lazar Markovic has completed a loan switch to Anderlecht until the end of the current campaign," read a short statement.
Elsewhere 20-year-old winger Harry Wilson has moved on loan to Hull City for the remainder of the season.
Stoke have completed the £14million signing of Badou Ndiaye from Galatasaray.
The Senegal international has agreed a four-and-a-half year deal after securing a work permit.
Ndiaye was unveiled by the club at half-time of their Premier League game with Watford at the bet365 Stadium on Wednesday.
Chief executive Tony Scholes told the club's website: "Badou was a player in great demand but from talking to him it's clear he always wanted to play in the Premier League and we are delighted he has chosen to fulfil that ambition with Stoke City.
"We are delighted with the business we have done over the course of this transfer window.
"All three players we have signed have real pedigree, have played senior international football and will really enhance the options Paul Lambert has within his squad."
Ndiaye faced a race against time to complete the paperwork before Wednesday's 11pm deadline because he did not qualify for a work permit and visa.
Personal terms were agreed before Wednesday but his international appearance record was not above the required threshold.

Tottenham have announced the signing of winger Lucas Moura from Paris St Germain on a contract until 2023.
The Brazilian has made only six substitute appearances this season, having fallen behind Neymar and Kylian Mbappe in the pecking order.
Moura, 25, moves to White Hart Lane for an undisclosed fee, reported to be £25million, and could make his debut in Spurs' trip to Liverpool on Sunday.
"It's a new chapter of my life, a new challenge, I'm so happy," he told the club's official site.
"I can play in the Champions League and it's a big objective for me. To make new friends is always a pleasure and I will give my best for the club. We have a lot of quality and we can win big things.
"I'm so excited, everything is perfect and I'm sure we'll do big things together. I want to play, to help the team. It's very strong and can win a lot of things, why not the Champions League?"
The Brazil international moved to PSG from Sao Paulo in January 2013 and played 229 times, scoring 46 goals.
He won four Ligue 1 titles, three French Cups, four French League Cups and five French Super Cups.
Moura has not played in the Champions League in this campaign so is eligible to feature for Spurs, who face Juventus in the last 16 of the competition.
