Not very smart to compare the age of a keeper with the one of a field player.
37 is a fine age for a keeper, not for a field player, ofc.
Navas should only serve as a temporary solution until the club makes money for better younger keepers.
Would worth a try since he'll come on a free, he has great experience and was a top keeper for a good part of his career, at least until a good young keeper can be brought at the club with all the economical shit they are into.
I wish I could share your optimism on the matter but can't.
I suspect they may still not want him out not even after such an injury and after missing the rest of the current season.
Haven't watched such an entertaining game for ages.
Credit to Flick for not complaining about lack of transfers or injuries yet producing some very nice attacking football and great results domestically, so far.
Didn't watch Leverkusen play this season but judging from the 6th place that they are on atm I don't think they are the same solid team from the last season.
