Campfield were crowned Liverpool Business Houses Premier winners following their 1-1 draw with The Bull.
Adding to their National Cup win over St Josephs, they crowned a brilliant season with a league and cup double.
The rescheduled, stop-start season caused headaches for many teams and leagues.
Upon the restart, the Campy went unbeaten their opening seven matches before the run came to end after they were edged out by Dovecot, from then they went on to go unbeaten for a further nine games, with two draws.
The league remained tight at the top until the very last day where Anthony Clarke’s side needed just a point to etch their name on the league title.
On the final day, they went behind shortly before the break after a well-worked goal was finished off by Josh Sumner.
But they equalised just after the hour mark when a free-kick was cleared by the hosts falling to James Barrigan who unleashed a phenomenal volley to restore parity.
Clarke told Off The Park: “(It’s an) unbelievable achievement from all of us to win what must surely be up there with toughest Sunday league in history.
“It was the toughest league I’ve ever known and we made it even tougher with the slow start but once we found our feet the winning mentality was there for all to see.”
He added: “I thought from the restart in April we was brilliant getting some big victories.
“But I’d have to say the way we bounced back from a rare defeat that saw us go on to win the National Cup the week and after then go on a six-game winning run in the league which sent us top with three games to play was the most important spell for us.”
Ryan Jones saved an early penalty in the National Cup final but the teams failed to make the breakthrough after 90 minutes. After just three minutes, the Campy broke the deadlock thanks to a thumping header from Elliott Nevitt.
“In terms of winning the two trophies that were on offer to us then but I don’t think any team was going to be perfect in this league. It was always going to come down to who handled the little setbacks the best. We had seven draws throughout the season but to only suffer two defeats in this league was an unbelievable achievement.
“I don’t think you can compare it (winning the double). The fact it was the first season every club in the city was competing in the same league as each other and not to mention the standard of those teams meant it was without doubt the most difficult Sunday league in Liverpool to ever win, in my opinion.”
He concluded: “For us to be the team that finished top of the pile is something that will go down in history and rightly so.”
