Santos' Brazilian winger Mateus Xavier may change clubs during the summer transfer window. The 19-year-old's situation is being monitored by Inter Miami, where Lionel Messi plays. Shakhtar Donetsk and Los Angeles Galaxy are also interested in the player. Xavier intends to find a club where he can receive regular playing time, a decision prompted by having made only five appearances for the first team. Santos relies on the winger but cannot guarantee him a spot in the starting lineup. His contract with the Brazilian club is valid until the end of 2028. According to reports in June 2026, Shakhtar Donetsk made an official offer for the player valued at about $5 million (approximately €4.7 million). Transfermarkt lists his current market value at €400,000.
