Arsenal are reportedly monitoring teenage Legia Warsaw goalkeeper Radoslaw Majecki, who could become the fourth player to join the Gunners from the Polish club in recent memory after Wojciech Szczesny, Lukasz Fabianski and Krystian Bielik.
Arsenal plucked Szczesny from Legia's youth team in 2006, before later sealing further deals for Fabianski and Bielik in 2007 and 2015 respectively.
According to Polish outlet Przeglad Sportowy, Arsenal are currently watching 19-year-old Majecki with a view to making him understudy to number one Bernd Leno. That would allow the Gunners to move on veteran Petr Cech, relegated to a backup role earlier this season.
