There could be a couple of Chelsea academy players who could make their Premier League debut because of the recent substitutions rule change.
Frank Lampard has called a number of academy and development squad players to train with the first-team in the past few weeks.
Although there is no complete list yet, some of them have posted pictures of the training sessions on their social media, such as Tino Anjorin, Armando Broja, Lewis Bate and Henry Lawrence.
Anjorin and Broja have already been handed their Premier League debuts when Chelsea defeated Everton at Stamford Bridge back in March.
Considering Lampard has given senior team debuts to more Chelsea players than any other previous managers, Lawrence and Bate may also have their first taste of Premier League football.
Especially with the recent rule change where the Premier League will allow teams to list nine substitutes and make five substitutions in a match (BBC).
In favourable situations, let’s say a comfortable 3-0 lead, Lampard may want to rest the senior players and give these youngsters a go.

Lawrence, 18, is a versatile England U19s international who predominantly plays as a centre midfielder. While Bate, 17, who has played for England U17s is more of an attacking midfielder.
Although Lampard might also find it difficult to fit these two considering his midfield options.
