New Sunderland boss Sam Allardyce is looking at alternative attacking options after inviting former Schalke forward Chinedu Obasi for a trial at the Premier League club.
The Nigeria international is a free agent after being released by the Bundesliga outfit during the off-season, where his career at the Veltins-Arena was beset by injuries.
Obasi was limited to just 35 appearances in all competitions for the Royal Blues in three seasons and he is currently nursing an injury, according to Allardyce.
The 29-year-old joined Schalke in 2012, initially on loan before he made the move permanent six months later following an impressive spell with Hoffenheim.
"There's a triallist in at the moment," Allardyce confirmed. "He used to play for Schalke but he's been injured.
"He's a Nigerian international and we are just seeing because he's got a reasonably good CV, in terms of where he's played before.
"He has been fraught with a bad injury, which is why he's not been fixed up with a club yet, but we'd like to see him for this week and perhaps next week.
"But I need someone who has an impact now, not in three weeks time, so it will be a difficult task I think. But he's here and if he can show us anything we haven't got then there maybe something we can do."
