'Unnecessary goals' frustrate Schalke coach Keller

BERLIN (Reuters) - Frustrated Schalke 04 coach Jens Keller blamed individual mistakes and 'unnecessary goals' for their opening 2-1 Bundesliga defeat by Hanover 96 on Saturday as the Ruhr valley club's poor start to the new campaign continued.

Keller was already under pressure following Champions League competitors Schalke's ignominious German Cup first round defeat to third division outfit Dynamo Dresden earlier in the week.
