Chelsea are determined not to be held to ransom by Benfica over prime defensive target David Luiz.

Chelsea have refused to raise their initial £16.5million bid for the Brazilian insisting value cannot be the minimum £20 million the Lisbon club want because he is ineligible to play for them in the Champions League this season, says the Mirror.

That may change if they fail to land either Gary Cahill from Bolton or Werder Bremen's Per Mertesacker.

Benfica are still playing hardball and expecting Chelsea's stance to soften.
