Reigning champions Buriram United will have to do without centre-back Osmar Barba for the 2014 Thai Premier League campaign after his move to FC Seoul was confirmed on Sunday.
The 25-year-old, who began his career with Spanish side Racing Santander, joined the Thunder Castle in 2012 and immediately established himself as one of their key players.
Osmar, who was vice-captain of Buriram, played an integral role last season as they won the treble of the league, FA Cup and League Cup, along with their impressive run to the quarter-finals of the AFC Champions League.
And while it looked likely he would be departing from the New I-Mobile Stadium after spending time on trial at Leicester City, it will be in the K League Classic where he will now ply his trade after his move was finalised.
Both Seoul, via an official press release, and the player, through his official Twitter account, confirmed that a deal had been completed.
The South Korean giants will be familiar with his abilities after he played against them in Thailand during last year’s Champions League group stage, although he missed the return encounter at the Seoul World Cup Stadium due to suspension.
Osmar also made a habit of finding the net during his time at Buriram and scored 13 goals in all competition for the club in 2013.
The arrival of the towering centre-back, who can also play as a defensive midfielder, at Seoul is likely to alleviate the blow of the departures of key duo Dejan Damjanovic and Ha Dae-sung.
Montenegro international Damjanovic has agreed to join Chinese Super League side Jiangsu Sainty, while captain Ha is currently in Beijing finalising a move to Beijing Guoan.
