But with the Premier League transfer window closing tomorrow, Boateng looks set to stay in the Bundesliga.
Robben, who has played alongside Boateng in six title-winning Bayern teams, indicated that he would be disappointed to see the World Cup victor leave the club.
Bayern want £45million for Boateng to leave permanently, which the Premier League side are unwilling to pay, and now they are once again looking to land Maguire - who is valued at £65m.
Pundits say Boateng is very interested in joining PSG and has rejected an offer made by Manchester United.
Boateng spent a season with Manchester City and fans speculated whether this could be the reason for his reluctance to move to Old Trafford.

After moving to the Bavarians in 2011, Boateng has developed into one of the world's best defenders, but the relationship between him and Bayern is said to have broken down. Bayern are facing last season's cup winners Eintracht Frankfurt this Sunday in the "Supercup". "We have Mats Hummels, Niklas Sule, Javier Martinez and David Alaba who can play in the central defender positions plus two youngsters".
