Liverpool face an anxious wait to discover if four of their key attacking players are available for selection against Tottenham on Saturday.

Roberto Firmino, Philippe Coutinho, Christian Benteke and Divock Origi are all doubtful for the Premier League clash at Anfield.

Firmino is recovering from a hamstring injury sustained in the Europa League match against Manchester United at Old Trafford 13 days ago.

Jurgen Klopp claimed last week that the key Brazilian was “close” to a return to fitness although the manager stopped short of claiming he would be back to face Spurs.

Striker duo Benteke (knee) and Origi (thigh) both initially trained with Belgium during the international break but pulled out of the squad and took no part in the 2-1 friendly defeat against Portgual on Tuesday night.

Meanwhile, Coutinho is set to be assessed by Liverpool’s medical staff when he arrives back in England on Thursday after his long-haul trip to South America.

A report by the Liverpool Echo on Wednesday morning claimed that the 13-hour journey back to Liverpool is expected to take its toll on Coutinho and the medical staff are worried he may be too exhausted to start against Tottenham.

Firmino and Coutinho are regular starters for Klopp’s first-choice X1 and would be expected to start against Spurs if fully fit.

Daniel Sturridge, who started for England in their 2-1 defeat to Holland on Tuesday, is the leading striker at Anfield but he was partnered by Origi in Liverpool’s last match, a 3-2 defeat to Southampton, as Klopp opted for a two-pronged forward line.
