Real Madrid continued their revival in the Champions League with a comprehensive 5-1 win over RB Salzburg on Wednesday.

One of the highlights of the evening was the introduction of David Alaba, who came on as a substitute just before the hour mark to help bolster the Real Madrid defence.

Alaba's return a huge boon for Real Madrid,According to AS, Real Madrid are delighted that Alaba is back to full fitness and ready to play football.

This is especially true given the fact that Alaba's return has allowed Los Blancos to shuffle their defensive pack a bit more.

Indeed, coach Carlo Ancelotti has finally been able to rest his top defender, Antonio Rudiger, who has been an ever-present in the Real Madrid starting line-up due to injuries.

Given the German's fitness problems, playing him on a regular basis has always carried the risk of injury.

But now that Alaba is back in the side, Real Madrid can finally juggle their ranks and use the Austria international as an ideal alternative to Rudiger.

At the same time, the reigning European champions will be cautious about starting the veteran defender, who is returning from a lengthy injury lay-off.

However, Alaba's mere presence in the dressing room could go a long way to solving Real Madrid's defensive woes as they prepare for a crucial part of the campaign.
