Real Zaragoza are still to finalise a swap deal involving Lazio goalkeeper Juan Pablo Carrizo.
Carrizo is moving to Spain in exchange for the permanent signing of Francelino Matuzalem at Lazio.
Real have agreed a 12-month loan for Carrizo with the option of signing the Argentine permanently for £10 million. However, there is a hold-up at Lazio's end which is preventing the deal from being signed off.
