Midfielder Thomas Hitzlsperger may be given the chance to resurrect his career at Everton if he can prove his fitness.
The 30-year-old is training with the Toffees with a view to earning a contract after he was released by Wolfsburg at the end of last season.
Everton assistant boss Steve Round says he has so far been impressed with the former Germany international, who has had spells in the Premier League with West Ham and Aston Villa.
However, Hitzlsperger has been dogged by injuries throughout his career and Round admits his history is a concern for the Blues.
Round told the club's official website: "I have been very pleased with him. Thomas is a long way off playing but we have given him the opportunity to come in and it is up to him now.
"We will assess him over the next couple of weeks. He seems a really good lad and I don't think I have seen him without a smile on his face.
"What will determine whether he gets a contract is his fitness. He has had a bad injury and we would want to see that he could sustain training.
"If he could do that, he would add quality and strength to our squad. He has got a history of playing at the highest level."
