Early years Berisha was born in
Malmö, Sweden, to Kosovan immigrants from
Podujevo, but grew up in
Norway, living in
Egersund, a town south of
Stavanger. He spent his early years at local club
Egersunds IK. Berisha spent three trial periods with
Premier League side
Chelsea between the ages of 14 and 15, whilst also spending time with
Manchester City and
Aston Villa. The latter two clubs offered him a contract, both of which he turned down in favour of staying in Norway. On 20 June 2008, at the age of just 15 years, Berisha made his senior debut for EIK against
Staal Jørpeland IL in the
Norwegian Third Division.
Viking Berisha signed for
Viking FK in March 2009. He made his
Tippeligaen debut against
Brann on 21 March 2010, coming on for
Vidar Nisja in the 85th minute. He started twelve league appearances that season, four in the starting line-up and all on the left wing. It was from the left that he scored his first professional goal on 31 October in a 1–1 draw against
Lillestrøm. Berisha kept his place in the side for the season ender against
Kongsvinger, where his
man of the match performance inspired Viking to a 3–1 come back. Before
Tippeligaen 2011, Viking manager
Åge Hareide talked up Berisha as one of the best players he had coached, and in May, he won the
Statoil Talent Prize, an award handed to outstanding young Norwegian footballers each month. Each winner is given the opportunity to donate a scholarship of 50,000 Norwegian kroner to the club he or she thought had the most importance to their development; Berisha chose to give the money to his first club, Egersunds IK. As with 2010, one of his season's highlights was a goal scored from an almost replicate 25-yard shot against
Lillestrøm on 3 July 2011. Throughout that year, Berisha duly became a guaranteed starter for Viking, playing 88% of possible playing time. Despite continuing to play on the left wing for most of that time, Berisha became more prominent in his favoured central attacking midfield position as the season went on, something Stig Torbjørnsen, one of Norway's most famous talent scouts, wished for prior to the season start. On 19 June 2011, Valon and his brother
Veton became the first brothers to play together for Viking in 22 years since
Jan and
Egil Fjetland played against
Molde in the
1989 Norwegian Cup final. Despite both moving to Viking from Egersund, it was the first time the Berisha brothers had played a senior game together. On 15 February 2012, the day after Berisha was called up by
Egil Olsen to play
Northern Ireland, his agent Jim Solbakken told
Stavanger Aftenblad: "We are already in talks with several clubs that have Valon Berisha high or at the very top of their list when the international transfer market opens this summer ... Now we just need to find the club that fits Berisha and who will pay a lot for him." To this, Berisha said, "I must be much better before I am ready for the league I aim to. I see [my next club] as an intermediate step, such as in the Netherlands [in
Eredivisie] which focuses on young players."
Red Bull Salzburg in 2017 In July 2012, Berisha signed a deal with
Red Bull Salzburg, joining the club at the same time as fellow Norwegian
Håvard Nielsen After a brief illness, he made his debut against
Admira on 18 August 2012. He twice assisted his compatriot Nielsen, and was involved in what was his hat trick goal in a 4–4 draw. He scored his first goal for Red Bull the next week in the 1–1 draw against
Wiener Neustadt, and scored another in the 4–0 victory against
Wacker Innsbruck on 1 September. Of his 27 Goals for Red Bull Salzburg in the Austrian Bundesliga 14 of those strikes have come from outside of the box. During the 2017–18 season Salzburg had their best ever European campaign. They finished top of their Europa League group, for a record fourth time, before beating
Real Sociedad and
Borussia Dortmund thus making their first ever appearance in the UEFA Europa League semi-final. On 3 May 2018, he played in the
Europa League semi-finals as
Olympique de Marseille played out a 1–2 away loss but a 3–2 aggregate win to secure a place in the
2018 UEFA Europa League Final Lazio On 3 July 2018, Berisha joined
Serie A side
Lazio, on a five-year contract. Lazio reportedly paid a €7.5 million transfer fee. On 4 October 2018, he made his debut with Lazio in the
group stage of
2018–19 UEFA Europa League against the German side
Eintracht Frankfurt after coming on as a substitute at 64th minute in place of
Sergej Milinković-Savić. Three days later, he made his first Serie A appearance by entering in the 85th minute of the 1–0 home win over
Fiorentina in place of
Ciro Immobile.
Loan at Fortuna Düsseldorf On 30 January 2020, Berisha joined

Eintracht Frankfurt after being named in the starting line-up.
Reims On 9 July 2020, Berisha signed a four-year contract with
Ligue 1 club
Reims and receiving squad number 14. Reims reportedly paid a €5 million transfer fee. On 23 August 2020, he made his debut in a 2–2 away draw against
Monaco after coming on as a substitute at 56th minute in place of
Dereck Kutesa.
Loan at Melbourne City On 7 September 2022, Berisha was sent on a one-year loan to Australian club
Melbourne City in the
A-League. He received the number 14 ahead of the season. A month later, Berisha made his league debut in a 2–1 home win over defending champions
Western United. On 11 February 2023, he scored his first goal for the club, from a
penalty kick, in a 4–2 win against
Perth Glory at

Danny Vukovic. City lost 6–1 to
Central Coast Mariners. On 9 June, after contributing 7 assists and 1 goal during his loan spell, Berisha returned to Reims. On 1 September 2023, Reims had announced that Berisha's contract had been terminated by mutual agreement.
