Chelsea boss Frank Lampard has favoured a 4-3-3 formation this season.
Ahead of the game against Wolves on Wednesday, Lampard has hinted he could dump the 4-3-3 formation and switch to the 4-4-2 formation he used against Luton in the FA Cup on Sunday.
“I thought the two of them [Mason Mount and Billy Gilmour] were great,” Lampard said.
“Their movement of the ball, their discipline as a two, which is very different from a three, means that it’s something we can look at going forward.
“We also wanted to focus on the front two, the nine and the ten, to make sure they come in and give us something and to make sure we don’t lose something in midfield. So it was a nice step.
“It’s something we can look at going forward. I’m forever considering the attributes of the players within the team and system. This is the process of this year.
“With new players and younger players, today was right for us. Is that a sure way forward? Who knows, but it was great to see the options it brought us.”
