Stefan Ivov Velkov (; born 12 December 1996) is a Bulgarian professional footballer who plays as a centre-back for Danish Superliga club Vejle.
Born in Sofia, Velkov began his football career with Slavia Sofia in 2005. He made his first-team debut on 27 July 2013, at 16 years 227 days, coming on as a substitute for Hristo Yanev in a 0âÂÂ0 away league draw against Cherno More Varna. On 18 December 2013, it was reported that Velkov was on trial with Manchester United. After the great debut season and a few trials in big European teams, Velkov got a serious injury, which took him out of football for a minimum of six months.
In March 2015, Velkov extended his contract with Slavia for a further three years. He returned to training in April, but he did not take part in any further matches, so he missed the entire 2014âÂÂ15 season.
Velkov returned to play in the first match of the 2015âÂÂ16 season against Lokomotiv Plovdiv as a substitute in the 88th minute.
Velkov scored his debut goal for Slavia in the league on 17 September 2016 in a match against Ludogorets Razgrad, lost by his team with 3âÂÂ1.
On 10 August 2018, Velkov signed for the Dutch Eerste Divisie team Den Bosch. He made his debut a week later, playing the full 90 minutes in a 2âÂÂ1 away win over FC Volendam. He scored his first goal for the club on 25 September, in a 2âÂÂ1 loss against Heracles Almelo in the KNVB Cup.
After a short stint at KFC Uerdingen he moved to MSV Duisburg in January 2021. He signed a new one-year contract on 27 May 2021. In the summer of 2022, he left Duisburg.
On 17 June 2022, Velkov signed with newly relegated Danish 1st Division side Vejle Boldklub, penning a deal until June 2024. On 29 May 2025, Velkov extended his contract with the club until June 2027.
Velkov represented Bulgaria at the under-16, under-17 and under-19 levels. On 1 June 2013, he made his debut for the Bulgaria under-21 side at the age of 16 years, 5 months and 22 days, making him the second-youngest player to debut for the team after Nikolay Mihaylov. On 25 March 2016 Velkov was in the starting lineup for the goalless draw with Wales U21. He served as the team captain.
On 14 March 2017, he received his first call-up for Bulgaria senior team for the match against the Netherlands on 25 March 2017, in which he was an unused substitute. Velkov earned his first cap on 26 February 2020, playing the first 75 minutes of the 1âÂÂ0 home loss against Belarus in a friendly game.
