Speaking at his media conference ahead of Tuesday's Champions League clash with Juventus, Mourinho - who's future at United has been the subject of intense speculation in recent weeks - said: "I'm happy here".
Alba played under Lopetegui for Spain before the coach was sensationally sacked shortly before the start of the World Cup following the announcement he was to take charge of Madrid after the tournament in Russian Federation. "I am not thinking about anything else other than tomorrow's game".
Former Madrid coach Zinedine Zidane's policy was for players to spend the night before games at Madrid's training ground residences.
Before the Brazilian struck against Levante, their last goal in any competition came in a 1-0 win against Espanyol a month ago, with them failing to score in games against Sevilla, Atletico Madrid, CSKA Moscow and Alaves. "You can not cry", and added, "I do not have to talk about other clubs". "I will be the coach tomorrow".
The 27-year-old now leads the way at the top of the charts with seven Premier League goal to his name - with Chelsea unbeaten in nine matches this term - and is the early favourite for Player of the Year. "If you are looking for a dejected coach, don't coming look here". It belongs to all of us, not just the coach. "We can still reverse this situation, which we know is not an ideal one". "It's calm, we're confident we can turn things around".More news: Russian fans injured after escalator collapse

The last time Plzen faced Spanish competition on the road in the Champions League was in 2011 when the club fell bravely to Barcelona 2-0 at the Camp Nou in the group stage.
The attacker moved to United in 2003 and was a part of the team that was dumped out of the Champions League by Mourinho's Porto in the last 16 - the coach doing little to endear himself to the Old Trafford faithful with his victorious charge down the touchline during a 1-1 draw in England after Costinha's crucial equaliser.
Real are third in the group, a point behind leaders CSKA, who play Roma.
Real Madrid will make the return trip to Plzen to meet the Czech champions on November 7.
