Lens want early recoveries to put Thauvin and the next receiver close to goal. Marseille have a working route from a midfield regain into Gouiri and the runners around him. Their meeting turns on which side can secure the first exit before the next pressure arrives.
Lens have combined through Hazard and Thauvin, while Marseille have connected Nnadi, Højbjerg, Gouiri and Harit in a short attacking sequence. Gouiri also carried into space to score at Leverkusen. Lens' recent defensive problems include switching play reaching a new box receiver and a separate failure to finish the job after the first intervention.
Ivanović is absent from the reported squad after starting against Como, leaving fewer forward and pressing alternatives alongside the continuing Sima and Édouard absences. Todibo and Gradit return as defensive options. Marseille have Harit back in the reported group, with Garcia already having replaced the absent Emerson in the European match.
Lens should test Marseille's first pass early, followed by Marseille looking to reach Gouiri before the home defensive assignments settle. The recently used midfield and defensive group gives that attacking outlet a practical base. That's why I'm siding with Marseille.
