Manchester City plan to use Jo as bait to land Valencia winger David Silva.
The News of the World says City are offering around £25million for Spanish World Cup winger Silva but are hoping that Valencia take a chance on Jo.
Valencia were in for the City striker before he moved to England and may be tempted by the offer. The Spanish club are short up front after selling David Villa to Barcelona.
Manchester United chief Sir Alex Ferguson has monitored Silva's form in the past, but believes he does not have the pace for the British game.
