Exeter Chiefs fly-half Ignacio Mieres says fellow Argentina international Gonzalo Camacho will make a big impact at Sandy Park.
Camacho, 26, switched from Harlequins this summer and will be available for Premiership action after September's World Cup.
"I have played with him before and also against him - and he is a quality player," Mieres said.
"He is fast and strong and he likes to tackle," he added.
"I have known Gonzalo for a couple of years and he is a really good guy - I know him pretty well.
"It's really good now to have another Argentinian player in the squad, especially as he's a great player and a really good lad too."
