Liverpool are on alert with Benfica warning Oscar Cardozo they won't go crazy to secure him to a new contract.

Record says Reds boss Brendan Rodgers has had the Paraguay international under consideration as a strike-partner for Luis Suarez.

It had appeared Cardozo was set to spurn the Liverpool interest to commit to a new Benfica deal.

But it's emerged Benfica have informed his camp that they won't meet his opening demands.
