Looking at the two games that Leipzig have played in the Champions League this season, there is certainly a reason why some people still doubt them when facing Liverpool who have successfully won two games in the Champions League this season whereas it was the opposite for Leipzig at the start of the Champions League this season. The home game against Liverpool as the third game for both of them in the Champions League this season could put Leipzig in an even more difficult position if Leipzig can't win the game considering Liverpool are still quite solid this season in any competition.
Previous Leipzig matches.
Atletico Madrid vs Leipzig ( 2-1 )
Leipzig vs Juventus ( 2-3 )
Leipzig always got a narrow defeat and even when playing against Juventus, Leipzig should have been able to hold the match to a draw because Juventus in the 60th minute only played with 10 players but Leipzig failed again.
Liverpool previous matches.
Milan vs Liverpool ( 1-3 )
Liverpool vs Bologna ( 2-0 )
Liverpool always performs better with very strong consistency and it is very surprising that playing away against Milan, Liverpool can win.
So, the conclusion is that Liverpool chances of winning are much greater even though they are only playing away but in fact Leipzig cannot perform perfectly at home. The only surprise that can happen is a draw.
