Frank Lampard’s Derby almost always lined up in a 4-2-3-1, 4-3-3 or 4-4-2 diamond, setups which allowed an attacking midfielder to burst into central spaces with players encouraged to take shots from distance. Managers tend to build teams in their own image, after all.

An average of 53.9 per cent possession in the Championship, 69 goals and 54 conceded suggests Derby were neither a potent attacking side nor an overly defensive one, comfortable against weaker teams but forced behind the ball when stronger sides came to town.

“I want my team to play good football, but on the other side of that, I want them to be really aggressive and win the ball back,” Lampard said earlier this year. “I don’t like to try and put myself into one style of play. I think it is important to be adaptable in terms of systems.”

What's changed at Chelsea?

The most obvious departure from Maurizio Sarri's Chelsea is how quickly Lampard’s players get the ball forward. Gone are the overly patient sideways passes to Jorginho, and in their place a much more direct, vertical approach.

This was evident in Chelsea’s first goal during a 5-3 win over Salzburg. Under Sarri, as the right-sided centre-back, Kurt Zouma's first pass upon receiving the ball from the goalkeeper would likely have gone wide or inside to Jorginho (tucked in to the centre of a defensive three in this example).
