Real Madrid are set to be boosted by the return of a number of key faces for the crucial Champions League clash against Galatasaray. Los Blancos travel to Istanbul for Tuesday's key match on Monday morning and will welcome back key names such as Eden Hazard and Toni Kroos as they bid for a first victory of the season in the competition to keep their hopes of progression alive. Zinedine Zidane fielded a much-weakened side in Mallorca on Saturday night and saw his side fall to a 1-0 defeat - their first league loss of the campaign. Hazard is set to return after being given permission to miss Saturday's match owing to the birth of his fourth child. The Belgian took part in training at Valdebebas on Sunday alongside the rest of the group. Lucas Vázquez also completed the full session in his recovery from injury and is set to be part of the squad to travel to Istanbul, while Kroos, Dani Carvajal and Raphael Varane are also expected to return. Luka Modric trained alone on Sunday and Gareth Bale completed gym work as both players continued their recovery from injury but it will be hit and miss if either are involved in Turkey.
