Oluwaseyi has agreed to a five-year contract with Villarreal, running until 2030. He has a good track record, scoring 10 goals in his last 24 matches.

The deal was made possible by the influence of Taj Buchanan, a teammate of Oluwaseyi's with the Canada national team. Buchanan has spoken highly of Villarreal to Oluwaseyi, helping him make the decision to join the team.

Marcelino expressed his enthusiasm for the new signing, highlighting Oluwaseyi's potential to bring depth, speed, and finishing skills to the team. He noted that Oluwaseyi's experience in a smaller but competitive league will also benefit him in adapting to Villarreal's style of play.
