Demba Ba insists his arrival at Chelsea has done nothing to affect Fernando Torres' position as the club's main striker. Ba made the perfect start to his Blues career after his £7.5 million (HK$93.4 million) move from Newcastle United, scoring twice in the 5-1 FA Cup third-round win at Southampton as Torres remained on the bench. Torres is expected to be restored to the starting line-up when Premier League rivals Swansea City visit Stamford Bridge for the first leg of their League Cup semi-final tonight, although Chelsea manager Rafael Benitez could pair the two strikers from the start. Ba's impact means Chelsea immediately appear much less reliant on the inconsistent Torres, and he may well challenge the Spain international's position as the first choice forward in the longer term. But he has made it clear that he sees Torres as the senior partner, as the Senegal striker attempts to establish himself at his new club. "I just want to enjoy my football. It's not about pressure, it's about playing a game I like, and that's what I'm doing," Ba said. "I'm here to help the group and the team; it's not about taking the position of someone else. "I know Fernando is the main man. I've just come. I will learn from people and I will learn from him as well, because his history is much bigger than mine." Ba also claims he has already benefited from playing in front of the European champions' playmakers, including Juan Mata and Frank Lampard. "It makes football look easy, I just try to run in behind and create space for the midfielders because I know when they have space they will be dangerous," said the former Newcastle and West Ham striker, 27. "When you have players like this, that understand football perfectly, you just have to run and the ball will come into your feet, and that's what I tried to do. "I'm very pleased. I saw it when I played against them, but they are world-class players and when you play with them it's completely different," he added. "They create spaces, provide good passes and they are very intelligent in their game." Swansea were held 2-2 by Arsenal in the FA Cup, but manager Michael Laudrup opted to rest a number of key players in that game, placing Michu and Pablo Hernandez on the bench, and omitting Ashley Williams and Angle Rangel from the squad. All are set to start at Stamford Bridge. "It is very busy, but when you play at the highest level, you always want to win," the Dane said. "When you play the big sides away from home it's special for the players. "If we can continue with this positive momentum it gives a lot to the team."
