Lopez has international and Champions League experience
Sheffield United boss Kevin Blackwell will not be signing midfielder Gerard Lopez following his trial at the club.
The ex-Barcelona man, 29, is likely to go and play in the United States.
Blackwell told BBC Radio Sheffield that it is difficult for players to show their capabilities in the short time they have on trial.
"It's difficult for them to get match fit - they have to impress in two or three days. We have a good squad, it's hard for them to break in," he said.
Spain international Gerard has played for Valencia, Alaves, Barca and Monaco and was at Recreativo Huelva last season.
Hear live and exclusive commentary of the Sheffield derby on BBC Radio Sheffield's Football Heaven on Sunday on 88.6, 94.7 & 104.1 FM, 1035 AM and DAB. All the build-up starts at 1200 BST.
