Messi is said to have informed new manager Ronald Koeman of his desire to leave Barcelona in the current off-season after growing disillusioned with the direction in which the club is heading.
Eto'o admits that any decision Messi will make about his long-term future, he will respect and cheekily suggested that the only way his achievements can be honoured is by renaming the club after the Blaugrana record-scorer.
Eto'o retired as Cameroon's all-time record goalscorer with 56 goals in 118 caps between 1997 and 2014.
Eto'o started his career with Real Madrid in 1997 before joining Mallorca due to limited first-team chances.
At Mallorca between 2000-2004, he scored 66 goals in 154 games before FC Barcelona snapped him up for €24m.
With Barcelona, the African sensation scored 130 goals and registered 40 assists in 1999 games over five seasons.
With Inter, he won the treble under Jose Mourinho and scored 53 goals over three seasons with the Italian giants.
In 2011 he joined the ambitious project of Russian side Anzhi, where he became the highest paid player in the world.
After the failed project, he joined Chelsea, where he scored 12 goals and registered seven assists in 35 games in the 2013/14 Premier League season.
A spell at Everton followed that lasted just one season.
Another short-term spell in Serie A with Sampdoria followed before he's move to Turkey.
With Antalyaspor, he regained his prolific form despite his advancing years with 44 goals 77 appearances.
Eto'o then moved to Konyaspor during 2018 and scored six goals in 14 starts before a switch to Qatar.
With Qatar Sports Club the two-time AFCON winner scored six goals in 18 games before announcing his retirement.
The Cameroon icon went on to explain that the club should do everything in their power to make sure he remains in Catalonia as he is unrivalled in world football.
"We are lucky in that at Barcelona, we have the best player in the world and of all-time, we have to do everything possible to ensure he finishes his career at Barcelona," Eto'o explained before opening up on the Bayern Munich thrashing.
"I really suffered myself with that defeat, not just for Leo, but for all of the lads. Someone who has never played the game will find it hard to understand, but these things exist in football - and in life too.
"Anyone can suffer a fall but you have to get up again and that is the most difficult part. The players, the bosses, the fans... I hope that we can lift ourselves up from this and begin to dream again for next season."
