Liverpool's performance this season has indeed been extraordinary, they played well and consistently and it's true they have won 1 trophy and are still in 2 finals which are very possible for them to win.
Liverpool has already won the EFL Cup title when they beat Chelsea on penalties and now they also have two other finals i.e the Champions League final against Real Madrid and the FA Cup final against Chelsea. Meanwhile, Liverpool are also still likely to win the Premier League title even though they are currently 3 points gap of Manchester City. I might believe Liverpool will likely only win 3 titles (EFL Cup, FA Cup and Champions League) but it's hard to expect them to win the Premier League as Manchester City are getting closer to the title.
now the points gap is 3 with Man City who are at the top of the table, with 3 games remaining this season maybe I think there is no hope for Liverpool to catch up again because Man City are also playing very well and they will be very focused on the EPL game, this is the only trophy for them to win after they were eliminated in the UCL semifinals.
Of course it's hard to expect Manchester City to make the mistake that led to the failure to win the Premier League title when the league only has 3 match left. Manchester City's performance so far has been very good so hopefully they can win all the remaining match, so I think Liverpool only have a chance to win 3 titles this season.
