Trent Alexander-Arnold is in danger of missing Liverpool's visit to the Santiago Bernabeu next month - with the Reds defender one booking away from a Uefa Champions League suspension.
The 24-year-old and the rest of his team-mates will face off against the 14-time European champions on Tuesday evening at Anfield in a repeat of last season's final at the Stade de France, which the Spaniards emerged victorious from.
Jurgen Klopp's side have accumulated eight yellow cards across their six group stage fixtures this season, with Alexander Arnold's tally of two - received against Rangers and Napoli - the most of any player within the Reds' squad. However, in line with Uefa rules the defender would miss next month's return leg if he was to pick up a booking against Real this evening.
