Derby County 0-1 Leeds United: Kemar Roofe goal gives Leeds win in controversial first leg

Leeds United have the advantage in their Championship play-off semi-final after a controversial first-leg win over Derby County at Pride Park.

Kemar Roofe's 15th goal of the season was the difference between the teams, the forward producing an excellent first-time finish from Jack Harrison's curling pass from the left wing.

Derby were incensed when assistant referee Eddie Smart persuaded referee Craig Pawson to overturn his award of a penalty to the Rams with 14 minutes to go, after Harrison had been adjudged to have fouled Jayden Bogle.

The home side also felt Leeds midfielder Mateusz Klich could have been sent off after he appeared to headbutt Fikayo Tomori in the chest as he got to his feet after going down under a challenge. He was given a yellow card over the incident.

The second leg is at Elland Road on Wednesday, and no side has ever made the Championship play-off final having lost at home in the first leg.

• Relive Leeds' play-off win over Derby

Leeds dominated possession and deserved their win, while Derby failed to have an effort on target in the match.

After a cagey first half, Roofe's opener brought the tie to life and he could have doubled the lead soon after, but his shot from the edge of the box was palmed away by a full-stretch Kelle Roos.

Pablo Hernandez should have got Leeds' second but, with the goal gaping, the Spaniard completely missed the ball from six yards out after Jamie Shackleton's cutback.

More controversy between Derby and Leeds

The overturned penalty, as well as Klich's confrontation with Tomori, were the latest controversies between these two sides this season.

Having initially given the spot kick, referee Pawson changed his mind after discussions with his fellow official and awarded a free-kick to Leeds.

Although Bogle did place an arm on Harrison, replays were inconclusive as to whether that was enough to put him off balance and cause the Leeds man to bring his opponent down.

This was the first match since United's 2-0 win over Derby at Elland Road in January was overshadowed by the 'spygate' affair and Leeds head coach Marcelo Bielsa's admission that he had sent a member of his staff to "spy" on the Rams training the day before the game.

Bielsa later admitted that he had sent staff to watch "the training sessions of all opponents", with Leeds fined £200,000 by the EFL for their part in the incident, which Bielsa says he paid himself.
