We do live in a world where people always want to attach blame and think solutions are easy. Take Arsenal at Bournemouth on Tuesday. Wenger out lot blaming him for Bellerin playing like a goat. The same player they would undoubtedly claim as the best RB in the PL.
Puel isn't blameless by any means but Long and Rodigruez shanking it 9 times out of 10 is not so simple to solve. Pretty sure he doesn't instruct them to do it,
