The former St Leonards, Rye United and Bexhill United boss stepped down last Friday morning having become frustrated by a number of off-the-field issues.
White said: “There’s been lots of things that have gone wrong and most of them aren’t to do with football; it’s to do with the off-the-field stuff.
“It’s a shame because that was the one job I was going to come back (to football) for. I really did thoroughly enjoy the football side of it and that club’s got some real talent coming through, but I felt like I lost the backing of the club.”
White admitted to falling out with first team player-manager Sean Ray over goalkeepers Matt Cruttwell and Joe Winchester, but said club chairman Dave Walters was courteous towards him and backed up his comments with actions.
The 50-year-old White, who arrived at The Pilot Field when the reserves were resurrected last summer, was also running the under-18s with Jack Stapley and driving the minibus to the under-16 team’s away matches.
“I was working for the club five days a week for nothing,” continued White. “And all the hard work just wasn’t appreciated.”
United’s reserve team game away to Camberley Town on Saturday didn’t take place because the U’s failed to raise a side for the Suburban League Premier B fixture, not because the pitch was waterlogged.
“I did everything I could to get the game played,” added White. “I encouraged all the staff I worked with to stay, I gave them all the phone numbers and I must’ve had 20 phone calls Friday night. I don’t know why they didn’t get a side up.” Stapley will now take over the running of the reserves.
