Leeds United trio Robin Koch, Stuart Dallas and Tyler Roberts all struggled in the Whites' 4-1 defeat to Arsenal on Saturday evening.

Marcelo Bielsa's side suffered another bad day at the office in the Premier League, being soundly beaten by the Gunners at Elland Road. According to Sofascore, the aforementioned trio were the home side's lowest-rated players of those who featured for at least 45 minutes.

Here's a look at the trio in question, with a delve into the underlying figures behind their lowly match ratings.

Robin Koch - 5.9

Koch had a tough night at the heart of the Whites' defence, playing his part in the team conceding four goals.

The centre-back won just one ground duel out of four and lost possession 11 times, not to mention committing two fouls overall.

The 25-year-old also played just three accurate long balls out of seven on a bitterly disappointing evening for the German defender.

Tyler Roberts - 6.2

Roberts was another Leeds player who struggled, as he failed to provide enough quality in the attacking third.

The Welshman recorded no key passes or accurate crosses against Arsenal and failed to complete a successful dribble, summing up his lifeless showing against the Gunners.

The 22-year-old was another player who was wasteful on the ball, giving it away 12 times.

Stuart Dallas - 6.3

A scorer of eight goals last season, Dallas has yet to get off the mark nearly halfway through the current campaign, and he was nowhere near breaking his duck yesterday evening.

The 30-year-old failed to win either of his two aerial duels and he made one error which led to an Arsenal shot at Elland Road.

Possession was also ceded 11 times by Dallas, which meant that he, Koch and Roberts gave the ball away 34 times between them, a shocking tally on a night when Leeds struggled badly.
