Swansea have tabled a £2million offer for PSV Eindhoven right back Santiago Arias.
The Colombia international is wanted by manager Paul Clement as he looks to bolster his squad ahead of next week's transfer deadline.
The 25-year-old defender has 32 international caps and moved to Europe and Sporting Lisbon from his homeland in 2011.
He was moved on by the Portuguese club's secondary side before joining PSV in 2013.
Arias found a home in the Eredivise and has made more than one hundred appearances for Eindhoven.
