Oxlade-Chamberlain’s place may well have come due to the absence of Jones, with the club confirming the 20-year-old suffered a knock to his eye in training, forcing him to miss out.
There is an irony, of course, that one of those players coming in, Tsimikas, was sporting a nasty black eye as he took part in Liverpool’s open session on Tuesday.
Gomez was not involved in pre-Atletico training, and it has now been explained that the centre-back is suffering from a calf injury, though no timeframe has been set for his recovery at this stage.
Liverpool have only named 11 substitutes as a result of Jones’ injury, with youngster Tyler Morton already part of the squad prior to the withdrawal of his fellow midfielder.
“Unfortunately last night we lost Curtis Jones, a really awkward situation – a finger in the eye,” Klopp told BT Sport.
“He will be fine, just takes a little bit.”
It is unlikely Jones will be sidelined for a lengthy period, but Gomez’s issue is more concerning.
