Arsenal has undergone a significant squad transformation with the departure of defender Nuno Tavares to Lazio on a loan move, while midfielder Albert Sambi Lokonga joins Sevilla on a season-long loan with a buy option. Tavares' loan deal includes a sell-on clause, potentially bringing in additional funds for Arsenal. Lokonga, after successful loan spells, now aims to develop further in Spain, where Sevilla has an option to buy him next summer. The Gunners negotiated a 25% sell-on clause for Lokonga, indicating a potential financial benefit for Arsenal in the future.
