Just examples I can see from good leagues would be:
Juanlu Sánchez, 22, from Spain ➤ Sevilla FC, since 2022 ➤ Right-Back ➤ Market value: €15.00m ➤ * 15/08/2003 in Montequinto , Spain
www.transfermarkt.co.uk
Vitinho, 26, from Brazil ➤ Botafogo de Futebol e Regatas, since 2024 ➤ Right-Back ➤ Market value: €8.00m ➤ * 23/07/1999 in Belo Horizonte, Brazil

Joe Scally, 23, from United States ➤ Borussia Mönchengladbach, since 2020 ➤ Right-Back ➤ Market value: €7.00m ➤ * 31/12/2002 in Lake Grove, New York, United States

All played at good levels, young, none of them would cost an arm and a leg.
Other than that, even if you go for experienced but unexciting players on loan like Tomiyasu or Maitland-Niles, neither are great, but literally anyone who is better than Patterson is an improvement.
