The former Liverpool defender had some harsh words for the Argentine.
The £30 million signing from Roma came to White Hart Lane last year but endured a frustrating debut campaign in north London.
Poor form - but also a string of injuries - hampered the Argentine's time at Tottenham.
This season, however, the 22-year-old has looked a lot more promising. But Carragher says he can 'never see' Lamela's Spurs career turning around. So far, he has only rated Christian Eriksen of last year's Tottenham signings.
"It’s why I look at Tottenham, who travel to Manchester City on Saturday afternoon, and wonder how it will end for the men who arrived 12 months ago, during the record-breaking transfer of Gareth Bale (someone else who has had no issues with a new league in his first season) to Real Madrid.
"Of all the players who arrived during that £100m spree, only Christian Eriksen looked good. But with Roberto Soldado, Paulinho and Erik Lamela you can never see it turning, irrespective of Spurs paying a fortune to sign them. They are not the first and won’t be the last."
