The midfielder made his debut in yesterday's friendly defeat to Borussia Monchengladbach.
"He's not taken too long to settle in and he knows quite a lot of the lads from England," said Carragher. "He's a good lad too and he's staying right in the centre of Liverpool, so a lot of the fans have seen him around.
"He loves playing here and being at Liverpool. You like people to get involved with the city and he's doing that from an early stage."
