Unsurprisingly, Thiago was part of Liverpool’s squad training on the eve of the Champions League trip to Napoli, but two young midfielders were absent.
Before the opening match of the Champions League in Italy, the Reds held an open session at the AXA Training Center on Tuesday afternoon, with the media in attendance at lunchtime.
It gave an indication of the strength of Jurgen Klopp’s side for the Group A tie, with his group still plagued by injuries a month into the season.
Jordan Henderson joined the absent list with a hamstring strain last week, while Fabio Carvalho suffered a dead leg in Saturday’s 0-0 draw with Everton.
Although Henderson was expected to miss the session anyway, there was also no sign of Carvalho among a 19-man group in the outfield.
Curtis Jones was also not among those tested by Klopp and his coaching staff of Pepijn Lijnders, Peter Krawietz, Vitor Matos and Andreas Kornmayer.
Youngsters Isaac Mabaya, Stefan Bajcetic and Melkamu Frauendorf were included, to cover the absences in defense and midfield respectively.
Another to miss out was Caoimhin Kelleher, despite having previously participated in full training, and 18-year-old Fabian Mrozek was called up to train alongside Alisson and Adrian.
Ibrahima Konate, Naby Keita, Alex Oxlade-Chamberlain and Calvin Ramsay are still unavailable due to long-term injuries.
Klopp still has a strong squad to choose from for the trip to Napoli, and the manager is set to make changes for the group tie, including Carvalho’s replacement in midfield.
There is a chance that at least one of Thiago or Arthur starts in the middle of the park, with Fabinho, Harvey Elliott and James Milner as other options.
Roberto Firmino could replace Darwin Nunez up front, while Joel Matip is in contention to replace Joe Gomez as Virgil van Dijk’s partner.
