Messi rewrote history on Sunday when he scored a brace in Barcelona's 2-1 win at Real Betis to bring his total goal tally for the year to an amazing 86, breaking the previous record of 85 goals set by Muller in 1972.
The 25-year-old is widely regarded as the best player in the world at the moment, and his goalscoring exploits for both club and country have made him the favourite to win this year's Ballon d'Or, an award given annually to the player who is considered to have performed the best in the previous season.
Muller himself led a deluge of tributes to the Argentina international following his record breaking goal, and Wenger, who joined in the chorus of praise for the diminutive forward, admitted he thought that the previous haul of 85 goals in a calendar year would never be bettered.
"With the biggest imagination, I would not have thought somebody would be capable to do that," he told Arsenal Player.
"Congratulations to Messi. He is just mesmerising. What he is doing is unbelievable.
"It looks so easy to score, and we are all tempted to say 'Let's walk on this pitch and score goals', because it looks so easy when he does it.
"When you have played football, you know how difficult it is to score one goal.
"To think that one player can score 86 per year, if you think you play nine and a half months, it's nearly 10 goals guaranteed per month.
"When you start the month, you know this boy will give you 10 goals. It's not bad!"
Messi will have the chance to add to his goal tally when Barcelona take on Atletico Madrid in their next La Liga fixture.
