Pundit Andy Hinchcliffe questioned Leeds United's decision to let centre back Tom Lees join Sheffield Wednesday during Sky Sports' coverage of the Owls' Capital One Cup clash with Arsenal.
Wednesday defied the odds to demolish Arsenal 3-0 at Hillsborough, as goals from Ross Wallace, Lucas Joao and Sam Hutchinson handed Carlos Carvalhal's men a stunning victory.
The goalscorers rightly took the plaudits, but one player who starred throughout was centre back Tom Lees, who shackled Olivier Giroud and made last ditch tackles to stop Arsenal from getting back in to the game.
The 24-year-old defender has established himself as a key player for Wednesday over the last year, having signed for the Owls from Yorkshire rivals Leeds United in the summer of 2014.
Lees came up through the ranks at Elland Road, but was surprisingly allowed to leave the club without much resistance under David Hockaday - and the Whites are no doubt regretting that transfer right now.
Speaking during the commentary of Wednesday's win over Arsenal, ex-Owls defender Andy Hinchcliffe told Sky Sports that Lees has been vital this season - and still can't believe Leeds let him go.
"He's played with Michael Turner and Glenn Loovens this season, and the heart of every good side is a strong defence," said Hinchcliffe. "I never really understood why Leeds let him go, but he's enjoying life in Sheffield."
With Lees, Turner, Loovens and summer signing Darryl Lachman all in contention for places in defence, Wednesday certainly have solid options to pick from in their back line.
Meanwhile, Leeds have struggled to find a consistent partner for Sol Bamba in defence, with Giuseppe Bellusci and Liam Cooper both producing errors so far this season - and fans may be wishing that Leeds had kept Lees rather than let him join Wednesday after his superb display against Arsenal.
