Leeds United manager Marcelo Bielsa threw his arms up in despair when Stuart Dallas slipped over in front of him during Saturday’s 3-1 defeat at Chelsea.

Northern Ireland international Dallas was receiving a pass out on the left-hand side by the touchline, with his boss watching on just behind him.

Unfortunately, he lost his footing while trying to control the ball, allowing Timo Werner to launch a break that resulted in Tammy Abraham firing wide.

After falling behind to an early strike from their former player Patrick Bamford, Chelsea hit back with goals from Olivier Giroud, Kurt Zouma and Christian Pulisic.
