Steven Gerrard has warned that England will match it with anyone at South Africa 2010 if the side can live up to its potential.The 1-0 victory over Slovenia ensures England's progression to the last 16, where it will face Group D winners Germany on Sunday.It was the side's first victory of the tournament, and prior to which the squad has been under immense pressure to succeed given its fans' high expectations.Gerrard conceded the players felt the pressure from the media and the public, and it was a tension-breaker to get the three points in the final group game."There is relief there because the lads were under pressure and we are all so glad to be through to the next round," Gerrard said."All games are difficult but it's about us now. If we turn up and play close to our potential we're a match for anyone.""We can do well if we play like we did against Slovenia, stick together, keep trying to improve and keep listening to the manager.""His ideas and what he wants from the team are spot on.""If we can deliver what he is asking we will be difficult to beat like we were against Slovenia."Gerrard said any slip up for the rest of the tournament, much like his side's drab 0-0 stalemate against Algeria, will cost England dearly."We have done it before when our backs were against the wall and people were out there doubting us.""We rolled our sleeves this time and produced the goods. We need to do that all the time.""To get to the latter stage of the tournament, you need to find that consistency now.""If we perform like we did against Algeria, I don't think we'll get another chance."Source: Soccerway.com
