Rangers have confirmed the signing of Dundee United striker Jon Daly.
St Mirren defenders Sean Kelly and Jason Naismith have signed new one-year contracts with the club.
Arsenal full-back Bacary Sagna is eager to distance himself from speculation suggesting he is being tracked by Paris St Germain.
The France international is being strongly tipped to be the next high-profile departure from the Emirates.
He has hinted in the past that he may be open to offers while a dip in form has left his position in the Gunners side under scrutiny.
Sagna is, however, keen to point out that he has had no contact with anyone at PSG and has made no effort to push for a move away from Arsenal.
He claims there was no substance to reports in January linking him with a move back to Ligue 1 and insists that it remains his intention to honour his contract in north London.
"The January transfer rumours regarding PSG? I am 100 per cent devoted to my club," Sagna told L'Equipe.
"I am only thinking about defending the colours of Arsenal until the end of my contract.
"The fans are angry with me because they heard about PSG's interest, but I am not responsible for that. I have never had any contact."
