Arsenal will be without Thomas Partey for the first leg of their Champions League semi-final against PSG after he picked up his third booking of the tournament on Wednesday night.

was handed a yellow card in the second half after getting involved in an argument with Antonio Rudiger. After being awarded a caution by the French referee, was clearly angered by his teammate as he pulled him away and shouted at him for his lack of discipline.

Rice himself, Jurrien Timber and Gabriel Martinelli all headed into the match walking a disciplinary tightrope, with each player knowing a yellow card would have seen them miss out on the semi-final first leg. It was obvious that Rice was fully aware of the rules surrounding bookings but what exactly are they in this new look ? football.london has taken a closer look.

What are the Champions League yellow card rules?

All yellow cards accumulated in the Champions League are fully reset after the quarter-finals. Sadly for Partey, his booking does count towards his overall total and thus he will miss the first leg clash with PSG at the end of this month.

Fortunately for Rice, who was booked for a foul on Kylian Mbappe in the area before overturned the decision and rescinded the yellow card, he is no longer walking a disciplinary tight rope. Instead, his tally has now been wiped for the big last four clash.

What happens if a player is booked in both legs of the semi-finals?

If a player is booked in both legs of the semi-finals, they do not miss the final should their team reach that stage. In fact, there is only one way for a player to be suspended for the final is if they receive either a straight or second bookable offence red card.

Who will replace Partey?

will be keen to decide on who will replace Partey in the first leg as quickly as possible. Oleksandr Zinchenko could be moved into the midfield three for that clash in his absence.

Alternatively, Mikel Merino could be moved back into his natural position and Leandro Trossard could play in the false nine role.
