I am sure that there are journalists who are trying to ask Klopp whether the Europa League season is already over because they will win the title anyway and I know how Klopp would respond to these guys. Maybe you should get the chance to tell him that they can cancel the rest of the competition and give him the trophy right away, then wait for his reaction!
There are other tough clubs in Europa, but these clubs have not proven their energy yet, still waiting for them to compete with the Reds for the title. Why do most individuals seemed to be very confident of Liverpool winning the Europa trophy this season? Because I don't understand, there's presence of other clubs that have the capacity of winning and drawing Liverpool, instead no one focuses on them. The only team that keeps gaining massive credits on winning the Europa title is Liverpool, however let's wait for the final outcome for the league, which of these teams will go home with the trophy.
The confidence is a bit odd I agree because being confident about winning a title requires a remarkable performance across all competitions with essentially zero mistakes all the way. Liverpool has had some problems in the Premier League although they are doing well at the moment, but they have also lost a game in the Europa League. It wasn't the most important game, but still a team that people are confident in winning the Europa League at this early stage of the competition should also pay attention to the little things and not give away a game in the Europa League like they did against Toulouse. This can also happen if the game is more serious against a stronger opponent.
I wouldn't call it a reinvention as they are still playing what they are notorious for, but they had difficulties bringing it onto the pitch last season. The way they play is very high intensity and I thought that players like van Dijk are not suitable for their tactic anymore because they declined in intensity. But it works again for them and they play their high pressing again. For some weeks I thought that this could come to an end for Klopp at Liverpool, but they have no reason to make any changes at all. They will be busy though finding new players when Salah also leaves the club, which could be next summer.
