This method seems to be duplicated in your project.

    {
        $expression = [];
        foreach ($this->getOpponent()->getReference() as $hisVar => $myVar) {
            $expression[] = $alias . '.' . $myVar . ' = ' . $this->name . '.' . $hisVar;
        }

        call_user_func([ $fetcher, $join ], $this->class, implode(' AND ', $expression), $this->name, [], true);
    }
}
