The Rouges et Blancs striker acknowledges that it would be a big blow if the Colombia star were to move to Real Madrid but is confident the club can survive without him
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 interest from the Champions League winners.
Goal understands Monaco are reluctant to allow the 23-year-old to leave the club and are demanding as much as £70 million from Madrid.
James joined the principality outfit last year for £35m 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.
