With Vinicius Jr. and Kylian Mbappe as guaranteed starters, the third spot was contested.
Alonso chose Rodrygo Goes, who provided an assist but was lackluster in a 1-1 draw against Al-Hilal at the FIFA Club World Cup.
Brahim Diaz, substituted in after the hour mark, made a significant impact with his work rate, energy, and quality.
Alonso is delighted with Diaz’s attributes, seeing him as a perfect fit for his tactical vision and a key player in both short- and long-term plans.
Diaz’s contract renewal talks have accelerated since Alonso’s arrival, with only his signature pending, as he now has a real chance to become a regular starter.
Previously, under Carlo Ancelotti, Diaz was a backup to Jude Bellingham and Rodrygo, but Alonso’s faith in him, highlighted by his cameo against Al-Hilal, could see him start against Pachuca, especially with Mbappe likely to miss the game due to illness.
