We should not have been surprised by Liverpool’s first Premier League defeat of the season at Watford on Saturday because a stumble has been coming for a few weeks.
The manner of the 3-0 defeat against relegation strugglers Watford was concerning, but we have seen since the turn of the year that the momentum has been slipping away from Jurgen Klopp's team.
They were magnificent in their 4-0 win at Leicester over the Christmas period and yet they have not managed to reach those heights since for whatever reason.
You could question whether it’s complacency as they are so far ahead at the top of Premier League or a dip in confidence from some key players, but the warning signs were flashing long before the game at Vicarage Road on Saturday night.
They have been finding ways to win rather than winning in style over the last few weeks and after doing well to dig themselves out of a hole against West Ham last week, they were finally undone a few days later.
Troy Deeney spelt out his approach to the game in his interview on Sky Sports after the win as he confirmed he targeted Dejan Lovren as Liverpool's weak link and his success in that battle was a key reason why Watford won the game.
Lovren can be bullied into submission by players like Deeney and when you throw in performances from Mohamed Salah, Sadio Mane and Roberto Firmino that were among the worst we have seen from the attacking trio in Liverpool shirts, it’s easy to see why they came up short.
Firmino's role is especially concerning because he is dropping too deep in a bid to get involved in the play and it means that when balls come into the box from wide areas, he is not in a position to finish them off.
This is one of the key reasons why he has not scored a Premier League goal at Anfield this season and the lack of bodies in the box is one area Klopp needs to correct heading into the final furlong of the season.
Of course, we need to have some perspective here and those celebrating Liverpool's defeat looked a little tragic when you consider the overall picture.
For the first big Premier League setback to come in March and when they are so far ahead at the top of the table highlights how magnificent this team have been in recent months, but Klopp has some big decisions to make in the next week and he has to be bold.
He has rarely been keen to field is first team in the FA Cup, but the result at Watford has to change his approach and he needs to put a strong team into battle at Stamford Bridge.
I saw Virgil van Dijk's interview after the game at Watford and he said on a couple of occasions that the next game was massive at Chelsea, which was a clear indication that he wanted to play on Tuesday night.
It was a strong message to his manager and I would hope all of the players who performed so poorly at Watford will send out the same message as an FA Cup exit on the back on the display at Vicarage Road would be a massive blow to this season.
Winning the Premier League title would ensure that these players will join the ranks of the greats at Liverpool, but there is more at stake here as this already fantastic season could end up being one of the greatest ever if they get it right from this point forward.
Liverpool are more than good enough to win the FA Cup and the Champions League if they are at their best and the next few days are a big test for Klopp and his staff as they look to get back to winning ways.
The first team players have just had a two-week break, so there should be no concerns about tiredness and I would like to see a strong team selected to take on a Chelsea side that has already lost eight times at Stamford Bridge this season.
Adrian could play in goal, Neco Williams might play at full-back, Joel Matip should replace Lovren in defence and Curtis Jones might get a chance in midfield, but I would be tempted to send out the team that lost at Watford and urge them to get it out of their system.
While history suggests Klopp won't take that approach, it is the way I would go because the FA Cup could now become a vital competition for Liverpool as they look to get back up to top speed.
The return match against Atletico Madrid in the Champions League is a week away and they need to go into that with a spring in their step, as they look to overcome a 1-0 first leg defeat.
If we were to reach next Wednesday morning with Liverpool out of the FA Cup and Champions League two months before the season ends, there would be a sense that this great Liverpool team have fallen off their perch.
Klopp and his players need to show they have the fire in their bellies to make sure that doesn't happen.
