Who's that playing for Manchester City? Team fields five debutants
You may not have recognised many of Manchester City's players in their 5-1 defeat against Chelsea.
The club gave a debut to five teenagers in their FA Cup fifth-round spanking.
Despite being one of the world's biggest teams, City claim they had no choice but to start players most people have never heard of.
They blamed the close proximity of the Champions League game away to Dynamo Kiev on Wednesday, which took priority for the club's senior stars.
Newsbeat takes a look at who those fresh faced teenagers were, and if they have a future in Manchester sky blue (or neon green).
Manu Garcia, 18. Attacking midfielder
The attacking Spanish midfielder plays in a similar role to David Silva.
The 18-year-old revealed his team-mate had told him "not to be nervous or scared, just be how I am in training".
He's a smart cookie too and seen as one of the jewels in Manchester City's youth academy.
Manu Garcia is taking a three-year online degree in sports science.
He moved to Manchester as a 15-year-old, leaving his family behind in Oviedo in northern Spain.
Aleix Garcia, 18. Centre midfield
Aleix Garcia has one cap for Spain's Under-18s.
He said after the game on Instagram that he was "very happy for my first team debut, not about the result tho, time to keep going now".
The midfielder joined in a £2m move from Villarreal last summer.
He was known to City boss Manuel Pellegrini from his time at the club and has recently been training with the first-team squad.
An industrious player but someone who might have a long wait to get near the City midfield again for a while.
Bersant Celina, 19. Attacking midfielder
Bersant Celina speaks fluent English and has lived in Manchester for four years. In fact, he lives close enough to the club's training ground to be able to walk to work from his flat in the city centre.
Despite growing up in Norway, he has chosen to represent Kosovo, where he was born.
He dreams of captaining his country in a World Cup.
He came on in the final minutes of the league defeat by Leicester City earlier this month and set up Sergio Aguero with a perfect cross.
A potential rough diamond.
Tosin Adarabioyo, 18. Centre-half
Tosin Adarabioyo is an Englishman making his full debut for the club.
A local lad from Manchester, he is strong in the tackle and confident on the ball.
He's already an England youth international.
Adarabioyo wrote on Twitter after the game: "Proud moment for me to make my debut today, but a very disappointing result."
Known for his determination, he made his Under-18 debut for the club aged 14 and was captain of that side at 16.
At 6ft 5in, he's a man-mountain but needs to bulk up to deal with the strength of the Premier League.
David Faupala, 19. Striker
Faupala had a lighter thrown at him after he scored an equaliser for City on Sunday.
He's a France youth international who has pace and is good in the air.
Faupala joined City last summer after his contract at French Ligue 2 side Lens ran out.
He never started for them and has spent very little time training with the Manchester City first team.
Even though Faupala has little senior experience, Watford tried unsuccessfully to sign him from Lens a year ago.
With Aguero and Bony fit it might be a while before he plays again.
