Salerno, who is now a sporting consultant at Watford, worked with Massimo Cellino in a similar role at Leeds United and Cagliari.
The Italian left Leeds following assistant manager Steve Thompson’s suspension in April 2015. Salerno seems to be happy at Watford at the moment and has outlined the contrasting situations at the two clubs.
“For me it is really strange, I know the kit-man, the analysts at Leeds. But this is football,” the Italian told The Guardian. “I have many friends at Leeds who I speak with regularly. The club is massive, the supporters are fantastic. It’s unbelievable support.
“You remember there were many problems, a situation with the coach. It was a bad situation with Thompson and all the other things. It was very bad for two months.
“The situation at Watford is good. They are improving every week and we are looking very good in the table with three months until the end of the season.”
Salerno was speaking ahead of Saturday’s FA Cup fifth-round tie between Watford and Leeds at Vicarage Road.
Watford will head into the game as favourites, although the West Yorkshire outfit are expected to provide them with a stiff challenge.
Head coach Quique Sanchez Flores has done a remarkable job at Watford, who got promoted from the Championship only at the end of last season.
As for Leeds, playoff hopes are virtually gone now and a mid-table finish looks likely.
