Manuel Neuer's legacy will most likely never be surpassed at Bayern Munich.

The now 33-year-old German goalkeeper needs no special introduction.

After all, we're talking about a player who's won everything there is to win: from the World Cup to the Champions League, Neuer has done it all and has achieved it all.

But just like every other legend of the game, there will come a time when his performances will simply not suffice anymore, especially given Bayern Munich's appetite and their aspirations in the world of football.

The Bavarians only have the best and will only accept the best.

For many years, Neuer was exactly that and most likely, he was the very best at what he does in his peak as almost no one in the world could compare to the fantastic German.

But time is cruel and he is already 33 years of age and quite frankly, it is showing.

Of course, injuries have played their part and Neuer has been on the wrong side of them for years now, suffering from multiple setbacks going multiple campaigns back.

And just recently, Bayern were actually linked with a man that could potentially take over the mantle and dethrone Neuer from his spot between the sticks - Bernd Leno.

Arsenal's shot-stopper, for all his qualities, has also struggled in recent times but his misfortune doesn't really stem from individual errors.

The Gunners are a shadow of what they used to be back in the day and despite having the 27-year-old in goal, they just can't seem to stop conceding, having done so 17 times in the ongoing campaign already.

But even with all of that being said, Leno still managed to average 4.1 saves per game, which actually even edges out Neuer's 2.8.

The quality is certainly there and even though the 27-year-old is not the first name on Bayern's list - that spot being reserved for Barcelona's Marc-Andre ter Stegen if The Sun's report is anything to go by - he definitely has what it takes it to start a new era with the Bavarians.

Overall, he has 11 clean sheets in 48 games with Arsenal but as we've already said, that is mostly down to their issues as a team rather than his individual struggles.

If Bayern really do pull the trigger, they will not be disappointed.

And neither will Leno, who might also want to abandon a sinking ship while he still can.
