Feyenoord has signed 24-year-old Spanish midfielder Javi López, who previously played for Deportivo Alaves, Real Sociedad, and Real Oviedo. The deal includes a penalty clause based on the number of minutes Javi López plays for the Rotterdam club. If Feyenoord fails to use the Spaniard for the agreed minimum number of minutes or matches, they will be subject to a financial penalty or compensation. The exact amount of this penalty is not known.

Javi López will face competition from Jordan Bos and Gijs Smal, with Bos ruled out until the winter stop due to injury and Smal still recovering from a serious injury. Mika Marmol, who was initially brought in as a central defender, has been playing on the left-back position in the early league matches.

Feyenoord's decision to sign Javi López with a penalty clause suggests that they are committed to giving him regular playing time.
