As is often the case at Anfield, Liverpool's plans have been hampered by international football.
The two-week hiatus is over and Premier League football is back, but Jurgen Klopp's squad is not the same as it was before.
Fabinho and Alisson Becker are unable to play this weekend against Watford as a consequence of Brazil playing against Uruguay in the early hours of Friday morning.
With COVID-19 impacting the footballing landscape and the Brazilian duo having to fly back from South America, the logistical problems have proved to be impossible to escape.

Fabinho and Alisson will both fly to Spain rather than England before meeting up with the rest of their teammates during the week to face Atletico Madrid in the Champions League.
Curtis Jones is another who will be absent for Liverpool against the Hornets, having picked up a knock while representing England's U21 side, and he joins Thiago Alcantara and Harvey Elliott on the midfield treatment table.
Suddenly, Klopp is having to manage without as much strength in the centre of the park, with only Jordan Henderson, James Milner, Alex Oxlade-Chamberlain and Naby Keita available to play.
The latter, who has encountered injury issues in the past, featured three times in six days for Guinea over the course of the international break, which again doesn't bode well for the health of Klopp's midfield department.
On the positive side, Roberto Firmino spent the whole of the break at the AXA Training Centre, and Diogo Jota has been passed fit by the Reds boss after returning early from the Portugal setup.
It remains to be seen how Klopp will utilise his squad for their upcoming bout against Watford, but the current situation suggests that 4-2-3-1 could become an option.
Unlike Liverpool's go-to 4-3-3 shape, 4-2-3-1 would accommodate the addition of a forward player in the team at the expense of a midfielder, with Jota and Firmino potentially able to start together alongside Mohamed Salah and Sadio Mane.
Henderson could form part of the midfield two alongside one of Milner, Keita or Oxlade-Chamberlain, and the back four would remain the same as usual given Trent Alexander-Arnold's return to fitness.
Adopting 4-2-3-1 would allow Liverpool to field two midfielders rather than three until Fabinho returns to the team alongside Jones, and the shape would also bring a fully fit Firmino into the side.
The formation is ultimately for the players, and given that Klopp has a unique situation to overcome at Vicarage Road on Saturday, a change in formation could be the best way to navigate it.
