Newcastle have been told they will have to splash the cash to land FC Basel defender Gaston Sauro, as they face competition for his signature from La Liga leaders Atletico Madrid, according to talkSPORT.
Alan Pardew is already considering transfer targets for next season having watched the Magpies campaign fizzle out badly over the past couple of months.
The Toon boss sees the defence as a priority, having watched his side ship another three goals in the home defeat to Everton last night.
24-year-old Argentine defender Sauro has been one of the stand out performers for the Swiss champions this season, and recently scored in the Europa League against Red Bull Salzburg.
Newcastle are understood to have been tracking his progress for the past few months, and have sent scouts to watch him in action.
However, La Liga leaders Atletico Madrid are also believed to be interested, meaning the Magpies will be forced to act quickly and offer big money if they want to secure his signature at the end of the season.
