World Cup winner Andre Schurrle believes Chelsea may have found the extra ingredients needed to win titles in Cesc Fabregas and Diego Costa.
The new Blues duo, signed for a combined £60million this summer, made an immediate impact as the title favourites opened their Barclays Premier League campaign with 3-1 win at promoted Burnley.
Former Atletico Madrid striker Costa lashed in a quickfire equaliser after Burnley had taken a shock lead while ex-Arsenal playmaker Fabregas was influential throughout and had a hand in two goals.
Asked if the pair could make the difference, Schurrle said: "Yes, I hope so. It was very good.
"I think for Diego it was a perfect start. For a striker to come in and score his first goal is always important.
"He played fantastic in the friendly, and he scored. And now his first goal in competition.
"Cesc was fantastic for me as well - he always had control of the game. He was always running; two assists.
"So it was a fantastic night for them both - but it was only the first match and we have to keep going."
One of the Fabregas assists, to put Chelsea 2-1 ahead, was for Schurrle - and came out of the top drawer.
After a mazy run by Eden Hazard and a link with Branislav Ivanovic, Fabregas volleyed a well-weighted first-time pass into the box for Schurrle to run on to.
The German timed his run perfectly and tucked the ball home with the final touch of a move that contained 25 passes.
Fabregas earned the praise of manager Jose Mourinho and after the Spaniard was linked with Manchester United and a return to Arsenal, the Blues are pleased to have him.
Schurrle said: "I think a player like Cesc - every team wants him.
"So we are happy that he decided for Chelsea. We are happy that he is a Blue now. I am 100 per cent sure he will help us this season."
Schurrle himself is playing catch-up after his involvement in Germany's World Cup win meant a late start for pre-season training.
The 23-year-old said: "I've only been training for two weeks after my holidays - it was from zero to 100, directly into team training and everything.
"So there's a lot of work for me, but I'm feeling good. I'm enjoying my game, I'm enjoying being on the pitch.
"I think the whole team played well. We had a lot of control, passes, good combinations. It was a lot of fun on the pitch."
