The new Tottenham boss walked into the dressing room after watching the 2-1 defeat from the directors' box at White Hart Lane.
Former Seville boss Ramos then introduced himself to the players before delivering a pep talk to his despondent troops.
Allen, who took charge of Spurs yesterday following Martin Jol's sacking last week, said: "I met Juande after the game as the players did. He came in and spoke briefly to them.
"He comes with a fantastic reputation for the superb team he built at Seville and the success they have achieved.
"He said: 'I'll see you Monday morning, we start tomorrow morning' which I think makes sense."
