PSG and RB Leipzig are aiming to book a place in the Champions League final for the first time – and Express Sport is on hand to bring you all the semi-final action live.
Kylian Mbappe is fit to start for PSG after a cameo appearance in the quarter-final win against Atalanta.
The World Cup winner has been struggling with an ankle problem in recent weeks.
PSG boss Thomas Tuchel said: “He played for 30 minutes against Atalanta and had no reaction and had six days since to work on fitness, so of course he can start.
“We will decide after training whether he can play 90 minutes.”
Leipzig boss Julian Nagelsmann has warned his team they will need to defend as a unit to keep out Mbappe and Neymar.
“You can’t foresee what Neymar and Mbappe could do, they’re top players. We need to defend them as a team,” he said.
“It’ll be difficult, but we need to make them work and put them under pressure.
“We have to avoid losing the ball, because PSG are very strong on the counter-attack, but we’ll try to take the game by the scruff of the neck.”
