Chelsea's deal to sign Nemanja Matic is being held up by Benfica's demands to have two Chelsea players included in the deal, according to reports in Portugal.
Reports on Monday suggested that Chelsea were in advanced talks with the Portuguese club over the transfer of the midfielder after bidding €25m for his services.
But Benfica aren't happy with the terms of the bid just yet and want at least one Chelsea player to be included in the deal as well to bring the deal up to the value of €30m.
Portuguese daily O Jogo has suggested that Gael Kakuta is one name being thrown in to the ring for possible exchange but the publication also says that Benfica would want another fringe player to join the team on a permanent basis.
It's an ironic situation for the Stamford Bridge outfit, who originally let Matic leave west London as part of the deal that saw David Luiz move in the other direction.
Benfica, worried about not being able to find a replacement for Matic in January, are understandably keen for a repeat of the situation, given the success Matic has experienced since joining the club.
But, according to the source, there are other options for Chelsea as well. If they're unwilling to see any of their squad players leave, they could up their bid by €5m to €30m, thus convincing Benfica to agree to a simpler deal.
A presentation was reportedly pencilled in for Matic early this week but, thanks to Benfica's tough negotiating, the deal is still some distance from being agreed.
