Thomas Hitzlsperger has started a two-week trial at Everton as he bids to secure a return to the Premier League.
Manager David Moyes is taking a look at the 30-year-old midfielder, who is a free agent since being released by Wolfsburg in June.
Moyes is keen to add depth to his squad, after seeing his midfield resources stretched by an early-season thigh injury to Darron Gibson.
Former Germany international Hitzlsperger knows the English game well, having played for Aston Villa early in his career before spending a season at West Ham.
His spell at Upton Park was affected by a serious thigh injury, and Everton will assess his fitness before deciding whether to offer him a deal.
"I have been very pleased with him," Everton assistant manager Steve Round told the Daily Mail.
"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."
