A powerful and supremely technical forward, Boksic had a string of illustrious clubs including Juventus, Lazio and Marseille on his CV when he elected to join Boro for £2.5m in the summer of 2000.
By that time, he'd won the Champions League, the European Cup Winners Cup, and Serie A and the Italian Cup twice, as well as finishing fourth in voting for the Balon d'Or.
So it may have come as a surprise to the footballing world when he moved to Teesside, albeit not to the Boro fans who had grown somewhat accustomed to some of the biggest names in football being linked with moves to the club in the late 1990s.
Though perhaps past his physical peak, the Croatian international retained the presence of mind and skill to win a place in the heart of Boro fans.
He scored twice on his debut against Coventry, the first of a dozen goals in a debut campaign that saw him pick up Supporters' Player of the Year.
The pick of the dozen was a goal against Leicester City that was important and audacious in equal measure as Boro sought a vital win to steer away from the relegation trapdoor. Boksic collected the ball in his own half, carried it into goalscoring range and pulled off a supreme chip over the Foxes goalkeeper.
He netted twice in memorable wins against Manchester United in a Boro shirt, once at the Riverside on Boxing Day 2000 and again at Old Trafford in 2002.
Injuries took their toll as his Boro career wore on, though Boksic managed a further eight goals in the 2001/02 campaign. After representing his country at the 2002 World Cup, the striker called time on his career at the end of the 2002/03 season.
