Speaking to the Lancashire Evening Telegraph, Souness said : "I can understand Alan Mahon wanting first team football. He's a smashing lad and this is an opportunity for him to go and re-establish himself."
"Ipswich are a good football club and Joe Royle is a good manager so I'm sure he will enjoy his three months there if he decides to go."
Souness' opposite number, Tractor Boys boss Joe Royle, was also delighted that the move had been agreed by Blackburn : "I've followed him from early on in his Tranmere career and I also watched him a lot at Blackburn as well.
"He's a left-sided player who possesses great skill. He can play wide or left midfield, he's a clever ball player, and a good deliverer of crosses and if I can get him then he will be an excellent addition to the squad.
"Over the past six months we've lost Jamie Clapham to Birmingham and Hermann Hreidarsson to Charlton, who were both specialist left-sided players, so we've been lacking in that area.
"Alan is someone who can redress the balance a bit but at the moment we have not been able to contact him. I just hope that he will fancy a move down to us."
