Similar players in terms of characteristics such as movement,intelligence,finishing etc but not in terms of style though..Both can play in the center as well as outwide.So i thought this is a valid comparison.

Hope i dont see the past achievements argument..Who would you choose right now out of the two

SES is way better on the ball.

atm i'd choose Muller because he is so versatile and also more experienced .

El shar is awesome though but the fact that he is scoring goals don't say all the story . How does he impact on the game when not scoring ?
He has an incredible potential but he can't carry them for too long . he is 19-20 ? he needs a partner in front ala henry-bergkamp : In my dreams , Muller - el shar or balotelli-El shar

Bojan is good but is not playing

Well, according to the GoalImpact stats (which calculate in a complicated formula that is based on the official game sheets of about 180 000 matches in about 100 leagues, how important a player is concerning the goal difference his team achieves), Thomas Müller's goal impact is exemplary.

Have to say...Muller is currently the better player, although this is SES's breakthrough season we have to be very careful in developing him...he can be moved to a central position later on.

Both of them display maturity beyond their age.

I don't agree with the fact that Muller is more versatile. How? Muller can play anywhere in the forward line, so can El Shaarawy while being as effective. While Muller is somebody who has many attributes that belong to a striker, Shaarawy has that of a fantasista.

Both are clutch players as well, So it is really close. I'll go for El Shaarawy because I feel that he has been more influential, but of course one can argue that it is a case of big fish small pond.

Tomas Muller for me
SES has been sublime this season, I just think that at the moment Muller's progression has taken him above SES, who is only in his second season with Milan
