Clare returned to Sheffield Wednesday from a loan spell at Gillingham in January.
Clare - who had made just one cameo appearance since returning from a loan spell at Gillingham in January - was omitted from Wednesday Under-23s' defeat at Huddersfield Town on Tuesday, prompting some to speculate that he - like teammate George Hirst - had been banished by the Owls as punishment for his failure to sign a new contract.
That theory was quickly dispelled, however, as Clare helped to secure Jos Luhukay's first league win as Sheffield Wednesday manager on an impressive full debut.
And while Clare was somewhat overshadowed by teammates Lucas Joao - scorer of both the Owls' goals - and Adam Reach - heavily involved in both - his efforts against Derby have not gone unnoticed.
Here's what Wednesdayites are saying about the former Nike Academy player on Twitter...
The moment our season changed? Sean Clare...in the first few minutes got the ball turned and ran at their defence. The whole place lifted!!— SWFC GIFS (@SWFCDebater) 13 February 2018
Sean Clare did everything I expected - absolutely brilliant and such a positive influence on the side. Really hope his contract gets sorted and he can stay in the side.— Lee Hicklin (@KivoLee) 13 February 2018

Tell ya what, a pre-season on the weights and Sean Clare could be the tall, powerful, athletic central midfielder we’ve been missing. Very impressed with him— A-P (@apnelhams3) 13 February 2018
Unbelievable performance tonight, Sean Clare was top class from start to finish along side pelupessy, time to build and progress from a strong positive performance #swfc— Bod (@billjoehughes) 13 February 2018
Well deserved win tonight, worked our bollocks off & defended like beavers. Clare did more tonight than butterfield has done all season he has to feature more often.— Andrew Scholey (@Scoz1985) 13 February 2018
Joao was quality & even Rhodes put a shift in all you can ask for when it’s not going your way. #swfc
