 Pablo signed a two @-@ year contract with Championship ( second @-@ tier ) club Birmingham City in August 2011 , at the end of the summer transfer window . The fee was undisclosed . He made his debut for the club in a 3 – 1 home defeat to Braga in the group stage of the Europa League . Away to Club Brugge in the same competition , he was knocked unconscious in a clash of heads with Joseph <unk> for which he received lengthy treatment ; in the tenth minute of the resultant stoppage time , Chris Wood scored a winning goal for Birmingham . Pablo had replaced the injured Curtis Davies in the starting eleven , but the concussion sustained at Brugge gave Davies time to regain fitness and his undisputed starting place alongside Steven Caldwell in central defence . After Caldwell 's season ended early through injury , Pablo returned to the team for the last few games , including the play @-@ off semi @-@ final defeat , and finished the 62 @-@ game season with 17 starts , of which only 7 came in the league .
