Newcastle boss Sam Allardyce has admitted he is still unsure of his best starting line-up.

Allardyce has been frustrated by his side's inconsistent form since taking charge at St James' Park over the summer.

"I don't know my strongest 11 just yet, but as each game goes by you get a little closer," he said in the Daily Star.

The Magpies remain unbeaten at home this season but have lost three out of five games on their travels.

"We've been a dominant force at home and that's encouraging, but my biggest concern is the away form," he explained.

"It's important the players take everything we're telling them on board.

"We need to become more determined to stop the opposition playing."
