However, the arrival of Mandzukic also means that Al Duhail's young forwards Almoez Ali and Mohanad Ali will fall further down in the pecking order when it comes to place in the Red Knights' starting 11.
Earlier, English newspapers had reported that Premier League club West Ham United's manager Manuel Pellegrini was pushing to signMandzukic. The club, who are based in the Duhail district in the city of Doha, announced the news of the deal on social media this afternoon.
The Qatari club have pulled off a coup bringing in the 33-year-old striker who won the UEFA Champions League in 2013 with Bayern Munich and reached the final of the 2018 FIFA World Cup in Russian Federation with Croatia.
Despite being heavily linked with the Red Devils once again, the 33-year-old has now chose to put pen-to-paper on a deal with the Qatari club.
He won the Champions League with Bayern in 2012-13 and represented Croatia on 89 occasions, including in the World Cup final.
The Croatian has scored 44 goals in 164 appearances for the Bianconeri, but the writing appeared to be on the wall when he was excluded from Juve's Champions League squad in September. He retired from worldwide football after the World Cup in 2018.
