The Colombia star enjoyed an excellent World Cup in Brazil, ending the tournament with the Golden Boot after scoring six times as los Cafeteros reached their first ever quarter-final, prompting heavy speculation that Carlo Ancelotti could look to bring him to Santiago Bernabeu in a €90 million deal this summer.
James joined the principality outfit last year for €45 million from Porto, scoring 10 times in 38 games as his side finished as Ligue 1 runners-up, and while Germain feels that they would miss his influence he is confident the club have the financial muscle to replace him.
"All the players have faith in the club's officials," the 24-year-old told L'Equipe.
"If James leaves, as he's considered as one of the best in Europe right now, it would be a huge loss. But Monaco can always buy new recruits. I'm sure we’ll have a team as competitive as last year."James is set to join up with his Monaco team-mates in Miami on Monday as part of pre-season preparations.
