He insists the France No1 is already a popular figure.
Caulker, who scored against Villa, said: “Hugo’s learning English and it’s coming on really good.
“He made a fantastic save in a one-on-one and proved his worth.
“We communicate fine on the pitch. He understands the English he needs to know and he’s very vocal. Off the pitch, he’s very humble and a good character.
“He’s had to be patient and he’s handled that fantastically well. The gaffer gave him the nod against Villa and I thought he did well.”
