"I worked with him for 18 months at Liverpool so I know what he can do," the midfielder told reporters.
"David had a good record at Liverpool but, with no disrespect to him, there were a lot of far bigger names in front of him at Anfield like Fernando Torres.
"He couldn't get too much of a look-in but, if he gets a chance here, he'll take those chances. At this club, the fans make you feel loved."
Shelvey was on the scoresheet for Swansea on Tuesday as they ended a run of eight Premier League games without a win by beating Fulham 2-0.
