If life was a straight line, then Chelsea will just have to maintain their exact squad of last season and will be able to win the Premier League again this year...but as we all know, life is far from being straight and most importantly, so is our lovely game.
Cahill talked along similar lines last week as well, able and willing to look at the big picture view as one of the most experienced players in the squad these days.
Chelsea hasn't made a lot of signings to the anger of manager Antonio Conte, however, they have strengthened up in the areas of midfield and defence with Tiemoue Bakayoko, Antonio Rudiger and Alvaro Morata joining them.
"Obviously a penalty shoot-out is a cruel way to finish a game, so no, disappointed and the next couple of days are going to be a disappointment but we need to get going and prepare for what's going to be an important season".
"He thinks all the time how he can change things tactically and if he can do anything better".
"If you have a player that shows you during the training session to be one of the best, you pick him to play, to shoot the penalty". He asks for the ball in behind, he holds the ball up and he can score goals too.
At the Premier League launch in central London on Wednesday, Conte would not be drawn into a discussion about Costa's future, insisting his position is "the same" as it has been all summer. "The player knew the decision, his agent knew the decision, clearly the lawyer has not been well informed", said a Chelsea spokesman yesterday.
Add in fractious negotiations over his new contract and a bitter feud with Chelsea striker Diego Costa and it's easy to understand why the former Juventus boss rates the challenge ahead as the most daunting of his glittering career.
"We are going to activate all possible legal mechanisms to hold Chelsea responsible for their behaviour, paving the way for Diego Costa's departure", Ricardo Cardoso told Spanish newswire EFE as quoted by AS.
"He will be a big miss". "I hope to try to work to try and improve our squad, to improve our quality and then to be ready to fight for the season". We have to keep the squad strong, but signing big players like that gives us a boost as well.
'I was looking at the programme here earlier and you look at the two teams there, the squads, Chelsea are nearly half of what the Arsenal squad is, ' he said on BT Sport.
