Reina is set to join the Bundesliga champions as backup for Manuel Neuer, ending his nine-year stay at Liverpool.
One of those years (last season) was spent on loan at Napoli after Brendan Rodgers brought Simon Mignolet to the club from Sunderland.
And now it seems Mignolet will continue as the Reds' undisputed no.1, with Bayern set to sign Reina for a reported fee of around £2.5 million.
Jamie Carragher played alongside the Spaniard for much of his time at Anfield and has wished him the best ahead of his move to Germany. According to Carragher, Reina was one of the best goalkeepers in Europe between 2006-09.
Good luck to @PReina25 top keeper and man. From 2006/09 one of the best in Europe. Kept a fair few clean sheets together!— Jamie Carragher (@Carra23) August 6, 2014
Looks like @PReina25 will have the role Pinto had at Barca under Pep domestic cup games.— Jamie Carragher (@Carra23) August 6, 2014
Reina's debut season on Merseyside saw him help Liverpool win the FA Cup, with the shot stopper proving vital in the Reds' penalty shootout win over West Ham United in the final.
The 31-year-old was involved in many memorable Champions League nights, as well, while he almost won the Premier League title in Rafa Benitez's penultimate season in charge.
Without the Spaniard, Liverpool's nearest challenger for Mignolet's place in Rodgers' starting XI is Brad Jones, who has seen some action in the club's pre-season tour of the US.
The Reds were linked with moves for Keylor Navas and Guillermo Ochoa earlier this summer but both goalkeepers have now moved to Spain, meaning Jones is likely to remain Liverpool's second-choice stopper unless a new target emerges this August.
