Speaking to the Daily Mail about the current state of affairs at Arsenal, Jens Lehmann said: "I never ever understood the Aaron Ramsdale decision.
"You have a good, brave English keeper at a big English club doing well and then you bring in a Spanish guy who's never played for a big club at that level — it just doesn't make sense.
"The goal keeper is the most important position in the team. If I were Ramsdale, I don't know how I would react because it's not easy at that age. When you're older, it's different."
Mikel Arteta opted for a massive change at Arsenal earlier this season, bringing in David Raya on loan from Brentford to replace Ramsdale.
The new goalkeeper has done well despite a few errors here and there although not every supporter is convinced by the manager's decision.
