Sheffield United boss Chris Wilder says he's delighted with the impact of Ben Brereton Diaz
The striker arrived in January on-loan from Villarreal.
Wilder said: "Ben's [Brereton Diaz] been a super signing for us. All three [Diaz, Mason Holgate and Ivo Grbic], once they get embedded in and get moving as Ben has done, will be positive signings for us."
"Mason will be and Ivo will be. It was a difficult debut for Mason and Ivo came out of a collision on the wrong side and has to serve his 12 days through concussion requirements and laws.
"But Ben's been fabulous to work with off the pitch, fabulous to work with on the training ground and he's delivered assists, goals and performances."
