Heung-min Son will not participate in Tottenham's Europa League match against AZ, as confirmed by head coach Ange Postecoglou. Son recently returned from a hamstring injury during their win over West Ham but missed training on Wednesday. Postecoglou stated that Son would not be risked for Thursday's game, with Tottenham aiming for a third consecutive victory after wins over Qarabag and Ferencvaros.
Richarlison, however, is available and might make his first start of the season. He returned from injury as a substitute against West Ham. "Sonny was a bit sore after the weekend," Postecoglou mentioned in his pre-match press conference. "He was never going to be involved tomorrow. [We will] leave him out of tomorrow, and see how he is from there."

Postecoglou expressed confidence in Richarlison's readiness, noting that he successfully completed the weekend and is now into almost the second week of training. "[He is] ready to go in terms of being available," he added. The coach highlighted the team's strong start to the competition, having faced different challenges in both games.
The team has also provided young players with exposure to European football, which has been beneficial for their development. "We've exposed some of our young players to European football, a positive growth from that," Postecoglou said. This experience is seen as an opportunity for growth within the squad.
Tottenham aims to maintain their winning streak at home as they continue their Europa League campaign. The team sees this match as a chance to build on their current form and gain more momentum in the competition. "From our perspective - here at home - it's a good opportunity to continue our form," Postecoglou remarked.
The absence of Son is a precautionary measure to ensure his full recovery before returning to action. Meanwhile, Richarlison's potential start could provide fresh energy and options for Tottenham's attacking lineup against AZ.
The strategic decisions made by Postecoglou reflect Tottenham's cautious approach towards player health while maintaining competitive performance in the Europa League. The team remains focused on achieving success in upcoming matches while managing player fitness effectively.
