Football was a totally different game 30 years ago.

There were no sports science teams and medicals leading to a transfer were not as stringent.

However, few medicals in football history can compare with that of John Wark, who walked through the doors at Melwood in March 1984. 

The Scottish international, who had starred in the famous football film 'Escape to Victory' alongside Pele, Sylvester Stallone, Michael Caine and company, was snapped up by Joe Fagan as a free-scoring midfielder from Ipswich Town.

He was about to join a team on the verge of a unique treble - Wark could not have imagined that signing for Liverpool would be as quite a simple a task.

Wark told Liverpoolfc.com: "I remember when Joe signed me and he took me and the missus for a cup of tea when we met him for talks in the hotel.

"I remember Joe saying to me, 'I don't know anything about finances, so sort that side of it out with the chairman, John Smith, and Peter Robinson'.

"The famous one is my medical. I went back to Anfield with Joe and we were in the Boot Room.

"Joe asked me had I sorted the contract out. I said yes, and we were talking about me looking for a house and things like that.

"The doctor then came in and I thought we were going to do the medical in the treatment room, not the famous Boot Room.

"He took my blood pressure, he asked me to touch my toes and then told me I had passed! That was my medical at Anfield and I just couldn't believe it."

Wark went on to play nine top-flight games and netted some crucial strikes towards the climax of the 1983-84 season as Liverpool recorded a league and Milk Cup double.

He was ineligible for the European Cup final in Rome but he was with the squad on that famous night Fagan clinched a treble in his first season at the helm.

What is abundantly clear is the huge amount of respect the players who played under Fagan have for the man and they feel he perhaps doesn't get the credit he deserves.

Wark insists his name should be included in the same sentences as greats like Bill Shankly and Bob Paisley.

He added: "Joe was a great manager and I had a lot of respect for him. He was like old school and he carried on the work of Shanks and Bob Paisley.

"Joe was such a nice man and I was so pleased for him that he won the treble which was very hard to win back then.

"Joe had very good coaches as well with men like Ronnie Moran and Roy Evans and they kept you on your toes. It was a privilege to be part of it.

"For me Joe is up there with the likes of Shanks, Bob and Kenny Dalglish. To get a treble at Liverpool you've got to be up there with the rest.

"He was a real father figure and we all had a huge amount of respect for the man.

"It was a great treble and we had a great squad. We had a great mix and a great team spirit. I knew the Scotland boys anyway, like Kenny, Graeme Souness, Alan Hansen and Steve Nicol, but we all got on well.

"We had a great manager and when you add that together you've got half a chance haven't you?"
