The Tottenham Hotspur defender is currently on loan in Spain.
The Argentine had fallen down the pecking order at White Hart Lane this season, making just one appearance in all competitions prior to his January switch. But as things stand there is no option to make the move back to Sevilla permanent in the summer.
That could change in due course, with Toby Alderweireld, Jan Vertonghen and Kevin Wimmer all impressing at Spurs this season. However, Monchi has admitted he may have to fight with Tottenham chairman Daniel Levy to get a deal over the line in the future.
Speaking to Estadio Deportivo, the Sevilla supremo said, “A month ago it was impossible for Fazio to leave on loan. Now he is here.
“But first let’s see if Fazio can perform like he did before; that would be the main argument for moving forward. From there we will fight with our friend (Daniel) Levy.”
Monchi also admitted that the centre-back showed a willingness to return to La Liga in a phone call between the two men, something the Sevilla sporting director appreciated.
It remains to be seen what the future holds, but if Fazio can get over his horror show of a second debut (when he was sent off against Celta Vigo after just 25 minutes) Monchi may give Tottenahm another call for further negotiations.
