UEFA Champions League: Guirassy unavailable, Dortmund and Betis level at halftime.

It's halftime at Signal Iduna Park, with Borussia Dortmund and Real Betis currently tied at 0-0. Although there were a few promising chances for both sides, neither team managed to find the back of the net during the first half.

The Germans tried to control the pace in front of their home crowd but faced a well-organized Spanish defense. Betis, on the other hand, effectively neutralized the opposition's attacks while posing a threat on the counter.

A key moment in the first half was the injury exit of Serhou Guirassy. The Borussia Dortmund striker, one of the team's key players this season, had to leave the pitch before halftime, a significant blow for Niko Kovač's men.

Everything is still to play for in this match. With the score locked at 0-0 and Guirassy's absence for the remainder of the game, the second half could bring many twists between two teams still searching for the opening goal.
