Liverpool legend Steve Nicol says Andrew Robertson's injury is a heavy blow.

Robertson suffered a dislocated shoulder in Scotland's Euro qualifying defeat to Spain.

"It's not a good time for him or Liverpool, that's for sure. We have spoken about Liverpool's back four being their Achilles heel," Nicol told ESPN

"But one of the better defenders, in amongst an Achilles heel, is Robertson. He has been as consistent as anybody at the back four.

"So, it's absolutely a disaster for Liverpool. Now, Tsimikas is going to have to play. And he isn't particularly a great defender.

"You are now starting with two fullbacks, Alexander-Arnold and Tsimikas, whose best part of their game is going forward and not defending. That's not good."
