Barcelona president Joan Laporta is set to meet with La Liga president Javier Tebas on Friday over their salary cap problem which is affecting Lionel Messi's renewal.

If the result of the meeting is positive and both parties reach an understanding, the possibility of Messi signing a new deal soon will increase significantly, says Sport.

Friday's meeting will not be definitive in terms of Messi's renewal, because there are still other issues to resolve, but it's currently one of the main obstacles.

Laporta and his vice president Rafa Yuste are carrying out the negotiations with Messi and his father, Jorge, who is also his agent.

There have been significant advances but the final OK is still lacking. The La Liga salary cap issue is a difficult one to sort out.
