Marseille have agreed a deal to sign Andre-Pierre Gignac from Toulouse for a reported fee of £14.75million.
The France international striker is expected to sign a five-year deal once he completes his medical at the Stade Velodrome.
The 24-year-old was top scorer in Ligue 1 during the 2008/09 season scoring an impressive 24 goals, though he struggled last season with a number of injury problems.
"A tentative agreement was reached Friday between Marseille and Toulouse for the transfer of Andre-Pierre Gignac, president (Jean-Claude) Dassier announced," the club said in a statement.
Gignac will have to wait to make his debut for the defending champions as a slight ankle complaint will keep him out of the weekend game against Lorient.
Marseille had also hoped to secure the signing of Nice striker Loic Remy, but the 23-year-old's protracted move has stalled over his medical.
Remy had been linked with a move to the Premier League, with Liverpool and Tottenham among the interested parties, but the forward agreed a deal to join Marseille for a reported fee of £12.3million.
However, a planned press conference was postponed on Friday as it emerged that Remy has a potential heart problem.
"We decided not to introduce Loic Remy because, late last night, a small problem was revealed reading the MRIs," Dassier said.
"The news this morning is reassuring, but we took this decision because what matters most is the health of players."
Club doctor Christophe Baudot believed that the problem was with Remy's heart.
"It's a mechanical problem," he said.
"Further investigations are planned for Monday in order to give clear answers. He will not play until all doubts have been erased."
The club had hoped to team up strike pair Gignac and Remy following their nightmare start to the new season.
The champions are currently slumped in the relegation zone following back-to-back defeats against Caen and Valenciennes.
