Yeah Mainz is very interesting lately and slowly they will take place in the top 3 as long as they are consistent with the game. You know, in the last match I was fooled while placing a bet in this match when Mainz playing with 10 players, I chose Frankfurt to make a comeback especially they play at home but unfortunately Mainz scored 3 goals 
well from here I think Mainz deserves to be in the top 3 and they are only 2 points behind to be there.
I also wonder why Frankfurt could not win their home match even though Mainz had a player shortage in the 21st minute or after Mainz got their first goal through an own goal in the 15th minute. Even though Frankfurt who played at home could dominate more in terms of ball possession, the team was only able to score one goal in the second half of the match so Frankfurt had to suffer embarrassment in front of their own supporters due to the defeat they experienced. So Mainz was really able to make a surprise so it is very appropriate for Mainz to be in the top 3 positions if in the upcoming matches Mainz can still play like that. well from here I think Mainz deserves to be in the top 3 and they are only 2 points behind to be there.
