Issue number 177 of the CIES Football Observatory Weekly Post presents the list of footballers trained by clubs qualified for the Champions League last 16 round playing in these teams. The number of footballers trained varies between 11 for Barcelona to only one for Manchester City and Napoli.

Among the 11 players trained by Barcelona, six play for the Catalan side. The remaining ones play for five different clubs still competing in the Champions League: Benfica (Grimaldo), Dortmund (Bartra), Napoli (Reina), Bayern (Thiago Alcântara) and Paris St-Germain (Thiago Motta). The youngest Barcelona's product, Rafinha, is already aged 24. This tends to confirm the decline of La Masia as underlined in issue number 163 of the CIES Football Observatory Weekly Post.

Four Champions League clubs have trained less than three players under contract with teams participating in the last 16 round: Leicester (King, Chilwell), Juventus (Marchisio, Kean), Manchester City (Schmeichel) and Napoli (Insigne). For these teams, the training and promotion of players from the youth academy is clearly not a priority.
