Championship: ex-Barca man not Blades bound
Sheffield United will not be offering midfielder Gerard Lopez a contract after running the rule over him in training.
Capped six times by Spain, the 29-year-old was keen to revive his career in England.
'It's difficult for (trialists) to get match fit, they have to impress in two or three days,' manager Kevin Blackwell told BBC Radio Sheffield.
He added: 'We have a good squad, it's hard for them to break in.'
