Partey was named in the Atletico Madrid starting line-up and the Ghanaian had a great game against the Blaugrana.
The 26-year-old gracefully dictated play in the middle of the park and came close to scoring after firing a shot from the outside of the box.
Although Diego Simeone’s men eventually lost the game, thanks to a last-minute strike from Lionel Messi, Fabregas reserved praise for Partey.
In a Twitter post, World Cup winner described Partey as a very good player after watching the midfielder star against Barcelona.
“Thomas es muy bueno,” Fabregas wrote, which translates as, “Thomas [Partey] is very good”.
Partey has been in imperious form this season, having nailed down a place in the Atletico Madrid first team.
The Ghanaian midfielder already has two goals and an assist in all competitions this season.
