The 36-year-old has learnt his trade in the Spanish leagues having held coaching roles at Elche, Malaga, and latterly Sevilla, from whom he arrives at White Hart Lane with new Head Coach Juande Ramos.
But now he is relishing the chance to work with what he believes to be one of the top sides in England, alongside fellow first-team coach Gus Poyet.
Marcos said: “To coach in the Premier League is a dream for me, and Spurs is one of the best teams in the country.
“This team has enough quality to improve their position in the league table, and we’re certainly going to all work very hard to get back to the top.”
Juande arrives at White Hart Lane with a big reputation having taken previous club Sevilla to two straight UEFA Cup successes and Champions League qualification.
And Marcos is certainly best placed to give an insight to fans having worked with him for the last four years at Sevilla and Malaga.
He said: “I know a lot about Juande because I have spent such a long time working alongside him.
“He’s a very good coach for many reasons. He’s very serious about his work, he has very clear ideas, he likes his teams to attack, but he also doesn’t like to concede goals.”
Our new first-team coach Marcos Alvarez admitted it is a dream-come-true to be coaching in the Barclays Premier League after taking his first training session at Spurs Lodge on Monday.
