Chelsea boss Luiz Felipe Scolari says he's planning to build his team around a small group of ever-presents.
"I have in my mind one idea for the team to play against Portsmouth, but until then I want to see how the players train. I have a minimum of 75% of the team in my mind but I need to know the other 25%.
"I know who my key players are. I have had 15 days with them and I know who is important for us to play more games than other players.
"You need to build a team around a few players in essential positions for important games and I now know who they."
