Thomas Muller is concerned about Bayern Munich's strength in depth in attack, but accepts it will be difficult to find a quality player willing to play backup to Robert Lewandowski.
Poland international Lewandowski recently urged the club to sign another striker to allow him the opportunity for more rests.
Hoffenheim's Sandro Wagner is reportedly a target Bayern are keeping tabs on, but Muller feels that any striker the club decides to go for will find life "complicated" playing second fiddle.

"We have no player who can replace Robert Lewandowski as a striker, being the type of player he is," Muller told BayernTV.
"On the other hand, as has been said many times in the past, it's complicated to find a backup, because Lewandowski wants to play all the time.
"Of course, when I get tired, it's easy to say I could really need a backup right now, but if that's the case, then every three months it's also complicated for 'Mr. Backup'.
"A couple of weeks ago, Lewandowski was having problems and it'd have been good to have a backup, but when the coach wants to play the backup every third or fourth game and Lewandowski is fit, that's not a good situation either.
"That's for the club bosses and the coach to discuss and, at the end of the day, make a decision on that matter. It’ll definitely be a good decision."
