Swansea have signed Andrea Orlandi on a free transfer from Alaves and striker Warren Feeney on loan from Cardiff.
Feeney made his move to Cardiff permanent during the summer
Orlandi, 23, can play anywhere down the left or up front, and has signed a one-year deal at the Liberty Stadium with an option to extend his stay.
Northern Ireland striker Feeney, 26, has signed a four-month loan deal.
"Andrea came over to Swansea back in June for a look around, and we've been trying to sign him ever since," boss Roberto Martinez told City's website.
"He will be a fantastic addition to our squad."
Feeney signed for the Bluebirds from Luton during the summer, after a loan spell towards the end of last season.
He has featured in four of Cardiff's five games this season, but faces competition for places up front at Ninian Park following the arrival of Robbie Fowler and Jimmy Floyd Hasselbaink.
