It is not just personnel options that Lampard has to manage but flexibility in tactical systems and shapes. In the second half of the midweek win in Krasnodar, the introduction of Mason Mount and N'Golo Kante led to a 4-3-3 being deployed, a change that opened up the game in the middle of the field.
"It gave us different angles of pass and an idea that we could press higher up the pitch," explained Lampard. "There were a lot of answers to things I had my own questions on and there were a lot of positives to it.
"We changed things around at times last year and it's something that served us well, whether playing three at the back or 4-2-3-1. When you're bringing new players into the club with versatility in their game, you're also then trying to find the balance for the whole team and what brings out the best from all the players.
"I keep saying that normally you have a month or six weeks in America or the Far East to focus on these things but we're doing that in real time so it's maybe normal that we've had to find different solutions in different games."
