da premier bet： Birmingham City’s accidental Carling Cup hero Obafemi Martins said he is unsure of his future at St Andrew’s.The Nigerian striker – on-loan from Russian club Rubin Kazan – scored one of the easiest winners of a Cup final when Arsenal goalkeeper Wojciech Szczesny spilt the ball into his path, with Martins obligingly tapping home to send Blues fans at Wembley into frenzy on Sunday.But with the winners’ medal in pocket, Martins said talk of a permanent deal to keep his place in Alex McLeish’s squad was premature.”I don’t know anything,” Martins told The Birmingham Mail. “I’m still on loan and I just want to be with the team, scoring goals, and we will see what is going to happen.”Martins said his decision to join Birmingham was vindicated by their last-gasp victory over Arsenal on Sunday, with City winning their first trophy since their League Cup triumph in 1963.”When Birmingham called me, I decided to come. They have the players that can play. I’m lucky to be here, and we have won at Wembley,” he said.
