Manchester United have agreed to let winger Zoran Tosic join Bundesliga outfit FC Cologne on loan until the summer. Tosic has failed to make any impression at Old Trafford since arriving 12 months go from Partizan Belgrade as part of a double-deal that included Adem Ljajic. The Ljajic option was discarded last month and the player has since gone on to sign for Fiorentina. And despite his £7m price-tag Tosic has never given any impression his slight frame could adjust to the demands of English football. He made just two appearances this term - both in the Carling Cup against Barnsley and Tottenham - although he clearly has ability judging by his frequent appearances for Serbia, that are likely to earn him a place at the World Cup. It does seem unlikely the 22-year-old will eventually challenge for a senior spot at Old Trafford, although Tosic refuses to give up hope that he can one day force his way into Sir Alex Ferguson's plans. "I don't believe I have had my final say at Manchester United," he said. "Hopefully my performances with Cologne will be my ticket back to Old Trafford."
