Al Qadsiah represented the Saudi Pro League in creating a sensation, stealing the public attention in this transfer window by successfully signing one of the best strikers in Serie A. Atalanta profited significantly from the sale of Retegui, breaking the transfer record previously held by Tonali when he moved to Newcastle. I think everyone can guess Retegui motivation for moving to Saudi Arabia, the lure of a high salary is hard for any player to resist.
With Retegui signing, Al Qadsiah will be a team to be reckoned with in the race for trophies next season. Last season, they finished fourth in the standings. Aubameyang returned to Marseille, he only lasted one season in Saudi. I think the very young Retegui can easily replace the role left by Aubameyang, the Italian striker seems to be able to live up to expectations.
Here we need to remember that Al Qadsiah is not one of the clubs under the sponsorship of the Saudi Public Investment Fund (PIF). Therefore they don't have a lot of funds available with them. This club is based in Dhammam and is owned by Saudi Aramco. It is encouraging that such a club is spending a huge amount of money (€65 million) on Mateo Retegui. This will improve the competitiveness of the league, and will decrease the gap between the clubs sponsored by the PIF and the rest.
