FORMER Wanderers keeper Andy Lonergan could be in line for an unlikely Liverpool debut today.

The 35-year-old raised eyebrows when he trained with the European champions during the summer due to a goalkeeper shortage and signed a contract after first choice Alisson was sidelined with a calf injury.

Lonergan, who made 62 appearances for the Whites between 2012 and 2015, was on the bench for the Reds’ Super Cup win against Chelsea as another new recruit Adrian proved to be the hero of the hour in the penalty shoot-out.

But manager Jurgen Klopp has criticised the behaviour of a pitch invader after an accidental collision with the Spaniard during the celebrations left him with an ankle injury, making him a doubt for the trip to Southampton today.

That means Lonergan could make a remarkable Premier League bow, the former Preston and Leeds man having been released by Middlesbrough in the summer after a loan spell with Rochdale.

Caoimhin Kelleher, a 20-year-old who has come through the Anfield academy, is another option.

Asked whether Lonergan would be ready to step in, Klopp responded: "Yeah. (Caoimhin) Kelleher is now in training as well, so we have them.

“If we have to make a decision, we have to make a decision.

"Adrian came in a week before, Andy Lonergan trained longer with us, played a half in one of the pre-season games."

Elaborating on Adrian's ankle, Klopp added: "Thursday it was swollen, Friday I spoke to him and he said 'it's much better than yesterday' but we have to see.

"He will not go for a scan. It went down already. You can imagine you have that and you fly four hours back and it doesn't help swelling, so he couldn't have played directly after we landed in Liverpool.

"But I saw him now, it's OK and it looks better. But a decision will be made on Saturday, no chance to make it earlier."
