Lucas Podolski showed how confident he really is by tormenting his former team . It is not easy for any player to play against his former team where he is worshipped and produce such a masterclass display . That prove the level of his confidence and professionalism . He will surely be without mercy against any team he has no connection with . Cologne is his team and he loves it . But he has certainly moved on . EPL teams beware of this new merciless ''killer '' .
