Media reports on Wednesday morning had suggested that Blues boss Alex McLeish was interested in signing the 26-year-old Austrian international striker but the player's agent, Georg Stanggassinger, insisted that Janko will not be leaving Salzburg in January. "I have heard and read something about interest from Birmingham in Marc, but I haven't had any contract with anyone from Birmingham," Stanggassinger told Sky Sports "He has a contract until 2013 and Red Bull do not want to lose him. "It is known English clubs have tried to sign him in the past and yes Marc would like to play in the Premier League in the future. "But, he won't move in the winter transfer window 100 per cent. "It is not possible to move in January but maybe in the summer or in a year he could move."
