In mid 2011, Tomislav joined NK Imotski.[citation needed] Despite being just 20 years of age, Mrcela was immediately a starter. Missing just one game all season, Mrcela made 29 appearances and scored a further three goals. Mrcela continued his good form into the next season and missed just one further game by January 2013.[citation needed] His good form led to a move to fellow second division side NK Mosor where he played out the remainder of the 2012–13 season.[citation needed]
After good performances at Mosor, he moved to top division side NK Hrvatski Dragovoljac.[citation needed] Initially Mrcela struggled, making just four appearances in the first twelve rounds but then became a mainstay in the starting XI.[citation needed] Unfortunately his side were relegated by the end of the season but Mrcela did enough to convince ambitious Zagreb side NK Lokomotiva to keep him in the first division by signing him on a four-year deal[3]
On 14 June 2018, Mrcela left Jeonnam Dragons to join Australian A-League club Perth Glory on a two-year deal.[4] During his stay at the club, he won the A-League and contributed massively to the team's success.[5]
On 17 February 2022, he moved back to Australia signing with Western Sydney Wanderers until the end of the 2021–22 A-League Men season as an injury replacement player for captain Rhys Williams.[9] After making 12 appearances, Mrcela signed a two-year contract extension with the club.[10]
Mrcela scored his first goal for the Wanderers on 15 October 2022 in a 1-0 win against Melbourne Victory.[11] After helping the club to their first finals appearance in 6 years, Mrcela left the club to join Uzbek side Neftchi Fergana.[12]
International career
Holding dual citizenship, Mrcela is eligible to play for either Croatia or Australia. On 10 June 2015, he was named in a 23-man squad for Australia before two 2018 FIFA World Cup qualifying matches against Kyrgyzstan.[13]
