Yes Liverpool has a huge advantage over Burnley, they have a better squad between both teams no doubt but again this is a game of football where anything can actually happen irrespective of the kind of team that's playing. I always try to keep my fingers crossed in games like this because sometimes unexpected things happens.
Burnley could not stop Manchester United from defeating them when they were at 2:2 I wonder what you think they can get with a Liverpool team that has everyone available for the game and Mo Salah, Isak and the rest of the squad is ready to play the game. Liverpool will definitely be defeated by a team in this season but I don't think Burnley is that team not this early not even when Liverpool is topping the league they wouldn't want to risk anything.
If we are talking about a team defeating or beating Liverpool in the Premier league, I am not the type that says never since we can't actually predict what may happen tomorrow, and I also don't under-estimate team no matter how weak they seem to appear.
But when it comes to Liverpool and Burnley, it will be an insult on Liverpool to even compare them to Burnley, Burnley can not beat Liverpool based on their current rating except something changes before or in the middle of the match, or that Burnley turned out to be Extra lucky, but on a normal strength to strength and tactics to tactics levels, Burnley can't withstand Liverpool especially in their coming match.
