The 28-year-old has struggled to ever find similar form to that of his five-year senior spell at St James' Park - which came to an end in 2011, and could well see a return back to the north east as a way to kickstart his career once again.
The Spaniard will face off against the Magpies, and his former manager Rafael Benitez, this weekend when the Red Devils welcome Newcastle to Old Trafford.
The Chronicle says a Newcastle switch is likely to depend on the club's takeover going through, adding that "although acquiring a proven Premier League forward is a priority for Benitez, a move for Torres could prove expensive" if he opts to pursue it. He was loaned out to Milan for the 2014/15 season but he struggled in Italy so moved back on loan to Atletico Madrid for the remainder of that season and then the season after. He scored 65 goals in 102 games.

Juan Mata is a more interesting case, given that he is again struggling for minutes in a Mourinho-managed team. Talks over a new contract have already started but there is, as yet, no sign of progression from either camp.
Torres' time in England started brightly but fizzled out after a goal shy three years with Chelsea.
He joined Atletico on a permanent in the summer 2016 and played 45 times for them in all competitions last season.
Despite being past his peak, Torres has plenty of experience under his belt and also boasted 81 goals from 142 appearances during his time at Liverpool which will likely make him a target of many clubs. Newcastle would be an ideal destination for Torres and would be a very exciting signing for their fans if Benitez can pull it off.
