Lazio are interested in Tottenham's Sergio Reguilon. The potential transfer would be difficult because of the player's high wages.
The Spanish player is a fringe player for Antonio Conte and is waiting for new opportunities. The player is not in a hurry to leave the club and would be willing to wait until January before deciding.
Sarri is looking for a left-back and had Marusic playing in that position for the first two games of the season. Lazio have identified Reguilon as reinforcement at the left-back position. His high salary demands would be a potential obstacle.
