Swindon Town manager Mark Cooper has described his side's thrilling 5-5 draw against Sheffield United in the League One playoff second leg as "torture".

The Robins were 2-0 up inside 10 minutes thanks to Ben Gladwin's brace, before Michael Smith extended the lead.

Jamie Murphy and Chris Basham then made it 3-2 and Steven Davies replied to Smith's penalty after the break.

Jonathan Obika looked to have settled it but late goals from Matt Done and Che Adams pulled United level on the night, ultimately in vain as Swindon held on to win the tie 7-6 on aggregate.

Cooper told BBC Sport: "It was torture. The worst game of football I've been through. I did not enjoy it at all. Going to Wembley hasn't sunk in because of the drama. It must be the best playoff game in history?"

Cooper's side will now take on Preston North End in the League One playoff final at Wembley on May 24.
