Andre Villas-Boas has revealed his desire to make Chelsea's squad perfectly balanced is the driving force behind his summer recruitment drive.
Villas-Boas declared a commitment to attacking football when he was appointed Blues boss this summer, something billionaire owner Roman Abramovich is said to want to see more of at Stamford Bridge.
But the new manager insisted that would not come at the expense of the defensive solidity for which Chelsea have become renowned, and said: "It's not by bringing in extra forwards or forward-thinking players that you become more offensive Maybe in the end you are punished at the other end and you could become exposed defensively if you do. You just have to create a balance."
The squad Villas-Boas has inherited are still searching for that balance judging by their opening two games of the Barclays Premier League season.
"What we are trying to achieve has reflected itself in both second halves at Stoke and against West Brom," Villas-Boas said.
"We are trying to find that 90-minute performance and consistent performance.
"But it takes time in the beginning because there is a radical change in the way you train and play.
"You can try to expect it in the first games of the season, but it's difficult to get it."
