Chelsea FC Women head into this afternoons Champions League round of 16 second leg against Atletico Madrid with a 2-0 lead and Maren Mjelde says the Blues remain focused on producing another good performance. . Chelsea were reduced to 10 players after just 12 minutes of the first leg but two penalty saves from keeper Ann-Katrin Berger, a converted penalty from Mjelde and a goal from Fran Kirby gave the Blues an important first leg victory at Kingsmeadow. . . With Chelsea having a 2-0 advantage going into todays second leg in Italy, Mjelde expects our Spanish opponents to come out fighting and the Blues defender says the Blues are fully prepared for a resurgent Atletico Madrid. . . She said. We know we are in a great position going into the away leg but at the same time its an important game for both teams. . . They need to come at us and win the game, so we are prepared for that. . . We have to focus on the task and then we will go from there. . Emma Hayes moved Mjelde to play alongside Millie Bright in the heart of the Blues defence following Sophie Ingles red card in the first leg. . . The Norway international did not look out of place and followed up with a solid performance at centre-back during our Womens Super League victory against West Ham United on Sunday. . . Mjelde believes previous experience in different positions throughout her playing career have helped her to develop into a player who is comfortable playing in any role. . . She said. I was playing with the boys till I was 15 and I played a lot of positions when I was playing there. . . I moved to the senior team and I got to play a lot of positions there so Ive never had one position. . . Ive always been the player who plays where the team needs me to play or where the manager needs me to play. . The switch to central defence for Mjelde meant a right-back role for Niamh Charles and the 31-year-old says she can draw on her own experiences to help the youngster. . . She added. I can put myself in their position. I have my experiences and Im a bit older now so I know how much it helps players when we communicate and give feedback during the game. . . For Niamh coming in, it was probably nerve-racking for her to come into a game where we had gone down to one less player. . . If she can get help from me and the players around her she will feel more safe and do her thing. . . She is an incredible footballer and I think she showed everyone that on Wednesday.
