Tottenham are challenging Arsenal for Sampdoria defender Joachim Anderson.
Arsenal have failed with two offers for the stopper and the Denmark international is open to a departure.
Gazzetta dello Sport says Juventus, Tottenham, Arsenal and Lyon are all in contact with Samp for Anderson.
Samp are seeking €35m to sell - with both Gunners' offers falling short.
Arsenal aren't expected to go higher unless they find a buyer for Shkodran Mustafi.
