Joe Ledley has urged former team-mate Jay Bothroyd to make the switch north of the border and join him at Celtic.
Bothroyd, 28, is currently a free agent after his contract at Championship outfit Cardiff City expired at the end of the season.
Wales international Ledley moved to the Scottish Premier League side in 2010 after spending six years with the Bluebirds.
"There will be a lot of interest in Jay as an England international who has just scored 20 goals for Cardiff," said Ledley. "He is big, strong and brilliant with the ball at his feet for a guy his size and only recently won his first England cap, so that proves how good he is.
"He's also quick and has proved he can score goals. I think he would be a good addition to the squad but it's not just going to be Celtic after him - a lot of Premiership teams will be as well.
"However, Celtic have a lot to offer. You don't get the opportunity at many places to play in front of more than 50,000 fans, who won't be bettered anywhere, and there's European football too."
Former Arsenal forward Bothroyd won his only England cap to date in the Three Lions' 2-1 defeat to France at Wembley last November.
