MARTIN Johnson is braced for a step into the unknown when England attempt to complete a series victory over Argentina in Salta today.

As a player, England’s decorated World Cup-winning captain tasted success in every major Test-playing nation except Argentina, the only destination he failed to tour.

Rested in 2002 and engaged in helping the Lions triumph against South Africa in 1997, England’s previous visits to South America passed him by.

Instead, Johnson is having to rely on the memories of Ben Kay, Lewis Moody and Steve Thompson for an insight on what to expect at the Estadio Padre Ernesto Martearena in Salta.

Kay, part of the 26-18 victory in 2002, has spoken of the hostility generated by the boisterous Pumas fans and Johnson is ready for a volatile atmosphere.

‘‘It would have been nice had I played in Argentina. In 1997 it was the same as this – a Lions year – and in 2002 Clive Woodward didn’t take a lot of us,’’ he said, ‘‘It would have been good to come here but I will finally get to see what it’s like on Saturday.

To win a Test match in Argentina has always been difficult.

‘‘Some of the guys toured here in 2002 and they’ve said it was a fantastic atmosphere and one of the best games they’ve played in.

‘‘We just need to be mentally right to get up for the game. There’s a little bit of the unknown about it but we will take care of ourselves.’’ England’s Test record since Johnson took charge in July last year is played ten, won five, with three of those reeled off in succession, culminating at Old Trafford last weekend.

Victory over the Pumas would nudge Johnson into credit and signal the revival that began during the RBS 6 Nations is gathering pace.

Just under a year ago England were exposed as a shambles on and off the pitch during their tour to New Zealand, but now Johnson’s simple philosophy is beginning to sink in.

‘‘It’s been a difficult year in some ways. I don’t know if it’s the Johnson message, it is the message about how you win Test matches,’’ he said.

Strengthened by the return of hooker Mario Ledesma, lock Rimas Alvarez Kairelis and prop Marcos Ayerza and hurting after the 37-15 thrashing at Old Trafford, Argentina will prove a far more formidable outfit on home soil.

‘‘The guys are in good spirits and are looking forward to the game, so I have a good feeling about it,’’ said Johnson.
