When asked about his interest in Wilson, Deila said: “That’s one of many names we are, of course, talking about but it is nothing serious. He is a good player.”
Hoops boss Deila played down reports of a move for NEC Nijmegen’s Iranian international winger Alireza Jahanbakhsh while adding that the club’s recruitment department are hard at work ahead of the summer transfer window.
He said: “We are working now. We have to use April and May to watch players and the scouting department is doing a very good job now, getting names in the positions we want.
“Now we just need to scout them, watch them as much as we can and talk with them so we know if they are the right type for Celtic.”
