Rangers manager Mark Warburton has confirmed that defender Oguchi Onyewu is training with the club,and could earn a permanent move to Ibrox.

The Daily Mail have confirmed that Rangers have handed a trial to the former US international centre-back at their pre-season camp in South Carolina.

Warburton has already strengthened his squad after winning promotion to the Scottish Premiership bringing in Matt Gilks, Clint Hill, Joey Barton, Jordan Rossiter and Niko Kranjcar.

Former Accrington pair Matt Crooks  and Joshua Windass have also arrived after they signed pre-contract agreements in January.

Onyewu, who played in the Champions League for AC Milan, has also enjoyed spells with Standard Liege, Newcastle, Sporting CP, Malaga and Sheffield Wednesday.

The much-travelled defender’s most recent club was Charlton in 2015.

“Oguchi is someone we have been told about by Niko Kranjcar’s agent. We are having a look at him in training and will see how he gets on,” said Warburton to the Daily Mail.

“This is the first time I have seen him and he will need the first couple of days to acclimatise in terms of the pace of the session and getting to know the boys.

“I don’t now what he’s been doing over the last year. He’s just one that was mentioned to us to look at and he’s very promising.

“He’s suffered injuries in the past and maybe hasn’t realised his potential. He looks like an athlete.

“I wouldn’t mind having a build like that. He’s got a great pedigree and it’s a position we are looking to strengthen.

“I will look at him for 10 days then say. “Thanks very much” and see what happens. If he does well then great, fantastic,” added Warburton.

The 34-year-old has represented his country 67 times after making his debut in 2004.

The powerful defender has vast experience playing in the Premier League, Champions League and Europa League and has also starred in seven different countries over his career.
