He made his debut for the club in a 3–2 home win against OB Odense, coming on for Pione Sisto in the 78th minute.

Mats Kristoffer Olsson (born 30 June 1995) is a Swedish professional footballer who plays as a midfielder for Danish club FC Midtjylland and the Sweden national team.

Born in Norrköping in Sweden, Olsson started his career at IK Sleipner.

When he was 13, Olsson was offered a trial at English club Chelsea, however he didn't attend and subsequently moved to IFK Norrköping.

When he was 16, Olsson garnered interest by European clubs such as Juventus and Ajax, as well as domestically from IFK Göteborg.

However, he signed for Arsenal in 2011 for £200,000 after having spent two previous trial periods with Arsenal.

While on trial at Arsenal, he played for Arsenal's under-16s against Crystal Palace and was invited to take part in the Ferrolli Cup and the Nike Cup as a result of his performances.

Olsson revealed that it was the drive of Arsenal Academy manager, Liam Brady, who persuaded Arsène Wenger to sign him, that persuaded Olsson himself to sign for Arsenal.

Olsson first played for Arsenal during their 2013 pre-season tour of the Far East.

He scored his first goal for Arsenal against the Indonesia national team at Gelora Bung Karno Stadium, Jakarta following a cross from Tomáš Rosický.

Olsson made his full competitive debut for Arsenal on 25 September 2013 as an 84th-minute substitute for Isaac Hayden in a League Cup game against West Bromwich Albion, in which he scored a penalty kick where Arsenal came out winners and proceeded to the next round.

On 2 September 2014, Arsenal announced that Olsson moved to FC Midtjylland in Denmark on loan until the end of 2014.

On 27 December 2014, the Danish club announced that a permanent deal had been agreed with Arsenal to make Olsson's loan move permanent, with the player himself signing a new three-and-a-half year contract.

In January 2015 he received his first call up to the senior Sweden squad for friendlies against Ivory Coast and Finland.

However, in his first training session with the team he broke his leg.

On 31 January 2017, Olsson signed for Allsvenskan club AIK.

Olsson was, in May 2017, called up to the Sweden's squad for the 2017 UEFA European Under-21 Championship to be held in Poland.

On 20 November 2018, Olsson played his first competitive match for Sweden against Russia at Friends Arena in Stockholm, in the 2018–19 UEFA Nations League.

Olsson started in the midfield and played almost the entire match.

On 7 January 2019, it was announced that Olsson had signed a contract with FC Krasnodar of the Russian Premier League.

On 21 July 2021, he signed a four-year contract with Belgian club Anderlecht.

On 31 August 2022, Olsson returned to his former club FC Midtjylland on a season-long loan deal with a purchase option.

In July 2023, he completed a permanent move to the club.

Olsson has represented Sweden at various youth levels and his style of play has been compared to former Swedish Arsenal players such as Freddie Ljungberg and Sebastian Larsson.

It ended as a 2–0 victory for the home side, which earned Sweden promotion to League A in the next edition of the tournament, as well as a play-off spot for UEFA Euro 2020.

In February 2024, Olsson collapsed in his home and was rushed to the Aarhus University Hospital and put on a ventilator.

His club, FC Midtjylland, put out a statement, in which they state the illness is related to the brain.

They also added that the condition is not related to self-harm or external factors.

On March 7, FC Midtjylland put out a statement saying that after numerous scans and examinations, doctors diagnosed that the collapse was caused by several small blood clots in both sides of the brain caused by an extremely rare inflammatory condition in the cerebral arteries.
