Lyon president Jean-Michel Aulas will not be flying to Portugal to complete the signing of Porto striker Lisandro Lopez this weekend.

Aulas revealed this morning that he was due to meet with Porto chiefs about the Argentina international and several other Porto players but the meeting has now been postponed until midweek.

A brief statement on the French club's website read: "Discussions are continuing with Lisandro Lopez and Porto.

"Taking into account personal obligations of the Portuguese directors, a new point could be reached in the middle of next week."
