Fernandes produced his best showing yet on Sunday as he scored and created an assist in the 3-0 victory over Watford, but according to Shaw Fernandes is making just as important a contribution off the pitch.
Speaking to MUTV, Shaw said: "He's had a massive impact. He's only been here for such a short time but it feels like he's been here for a while.
"You can tell he was a leader at Sporting and I think he wants to bring that leadership skill here to help the team as much as he can off the pitch as well as on it. Hopefully he can keep that up, he's not been here long but he's already shining for us and it's great to see."
