Manchester City were mounting a comeback against Barcelona on Tuesday when Gael Clichy picked up a second yellow for an ill-advised tackle on Dani Alves. It wasn't reckless or dangerous, but just unneeded when they were in the ascendency.
Without the France international, Aleksandar Kolarov is the most likely option to play at left-back for Manuel Pellegrini, although Bacary Sagna could deputise there at a push.
City have three league games before they travel to the Nou Camp for the return date of their Champions League last-16 clash with Barca and how Pellegrini uses his available full-backs could be crucial, but it could give the Chilean coach a chance to blood one of City's impressive youngsters.
Pellegrini has to decide between Clichy and Kolarov against Liverpool on Sunday. If he is set to play against Barcelona, it would make sense to bring him in before the second leg. The week of the trip to Barcelona, City face Burnley away; Clichy would be best used at Turf Moor. In the middle of the run City take on Leicester City at the Etihad Stadium and that would be the perfect opportunity to bring 18-year-old Spanish defender Jose Angel Tasende - otherwise known as Angelino - into the first-team squad.
With the investment Manchester City have made into the Etihad Campus, sooner or later they have to give youth a chance and this would be the perfect opportunity.
With 10 first-team players and a youngster, the home side should still have more than enough to beat Leicester, especially at home.
There is a fear factor from the bigger sides that seems to restrict them bringing through young players unless there is a huge injury crisis, but that is never ideal. If Pellegrini's side are to start developing a culture of bringing through young players, games at home against teams in the lower half of the table are perfect for rewarding players that have impressed under Patrick Vieira.
Sometimes you have to make a decision whether or not a young player is going to be good enough to develop into a first-team player, but until you give them a chance, it's near impossible to tell just by judging on training sessions.
Angelino has been excellent for Manchester City's Elite Development Squad and with his wonderful left-foot and superb ability on the ball, he fits into Pellegrini's ethos and has a style similar to Pablo Zabaleta on the opposite flank.
The Spaniard played his part as City's Under-19s qualified for the quarter-finals of the UEFA Youth League and the natural next step is to see how he copes with a senior outing.
He is quick and strong and looks comfortable in possession all over the pitch. Sometimes he is stifled a little on the left by the movement of Brandon Barker in front of him on the wing. The winger likes to stay wide and takes away some space for the left-back to exploit. With City playing a narrower style in the first-team, there would be space for the youngster to attack.
Although they are chasing Chelsea for the Premier League title, squad rotation and competition for places is important to keep the squad motivated. This suspension for Clichy could be the perfect opportunity for Angelino to make his first-team debut and if he rises to the occasion, it could just save the club a few million pounds in the transfer market this summer.
