The key defender has been out of action since October after suffering a shoulder injury while on international duty with Scotland.
To make matters worse for Liverpool, back-up left-back Kostas Tsimikas broke his collarbone in the draw with Arsenal in December, resulting in Joe Gomez filling in on that side of the defence.
Robertson wasn’t expected back until February, but on Tuesday Lijnders said that the 29-year-old is available for selection for when the Reds travel to Craven Cottage on Wednesday night.
‘Robbo trained yesterday with the team. It’s now 13 weeks, he had his meeting with the surgeon to make sure that everything is right to go into full contact – it’s clear,’ he said in his pre-match press conference.
‘So he did a lot of work and really good rehab throughout the last period, so he’s fit in terms of sports science. Now he has to get fit with proper team training.
‘So that’s a big, big advantage to have him back. We were waiting for a long time – he’s one of our captains. I just met him in the canteen and he said, “Pep, I have my tracksuit with me!”. So he’s pushing himself into the squad, so that’s good. He will travel [to Fulham].
‘Is he available to play? Yes. Medical team said it is a coaching decision, so he is in!’
In addition to Robertson, Curtis Jones has also been passed fit to play after a thigh issue, but the semi-final has come too soon for Trent Alexander-Arnold and Dominik Szoboszlai.
But the pair could be ready in time for this Sunday’s FA Cup fourth-round clash against Norwich, with Lijnders adding: ‘Trent is progressing well through his rehab, working hard – how he is as a guy, knowing how important the next weeks are.
‘But he will back in the end of the week for team training, so hopefully he will be available for the FA Cup.
‘Dom trained yesterday with us, just one small-sided game, one-touch game, but played good, felt good, did some extra work with the sports science team. He is ready but tomorrow comes too early for him, so he will be ready for the weekend if nothing goes wrong.’
Liverpool lead Fulham 2-1 from the first-leg and should they reach the final at Wembley they’ll face either Chelsea or Middlesbrough who play on Tuesday night.
