Sheffield United manager Bryan Robson will make a decision before next week on whether to sign former Celtic defender Jean-Joel Perrier Doumbe. Doumbe, 28, has been training with the Blades, and is out of contract with French club Rennes.
Robson told BBC Radio Sheffield: "I have been impressed with him and he comes with really good references from people I know within the game.
"I'll continue to have a look at him and then make a decision on Saturday."
