City come highly recommended for JJ
Svensson, who left Carrow Road in the summer, played with the Finn at Charlton and, despite having had some stinging criticism for Alan Curbishley since leaving the Valley, was ditsinctly more glowing in his praise of Nigel Worthington.
"I'm good friends with Svenny, and he had only good things to say," said Johansson, who made his debut as a second half substitute in Tuesday's defeat at Reading. "There were a few clubs I could have gone along to, but I had a think and spoke to Nigel Worthington and made my decision after that."
JJ, who said he had also sought advice from Kevin Lisbie, was also open to the idea of his stay in Norfolk extending beyond the end of the season.
"I would definitely think of a permanent move. I have an open mind," he said. "I'm here for a fresh change and I want to do well. We will see what happens."
Johansson could be in line for a full debut alongside fellow new boy Robert Earnshaw in Sunday's eagerly anticipated East Anglian derby.
