Manchester United are making progress with a deal to sign Ivan Perisic from Inter Milan, Sky sources understand.
Perisic's price has been a sticking point in protracted negotiations between the teams, with Inter holding out for £48m for the 28-year-old.
The Serie A side also enquired about the possibility of United's young French forward, Anthony Martial, going the other way in the deal.
But Inter are now in advanced talks to sign a replacement for Perisic - Keita Balde from Lazio - and that could smooth the way for the Croatian to move to move to United.
Perisic was given permission to leave Inter's training camp in the Alps on Saturday to return to Croatia to see a "trusted dentist" because of a "tooth abscess".
United have brought in Victor Lindelof and Romelu Lukaku already this summer but Jose Mourinho has made it clear he wants at least two more signings before the transfer window shuts on August 31.
"We don't have our door closed. We are not happy with just Lukaku and Lindelof. We need more," Mourinho said.
"We wanted four, so I could say 50 percent of the job is done, but I won't say that because it's so difficult. I wouldn't like to be in Ed Woodward's position, negotiating, because everything is really difficult.
"Maybe we don't get two, maybe we got one, but we need one to give us more options and balance. We have players in the squad that cannot play football for the next few months; players like Marcos Rojo, Ashley Young."
