Exactly.Brendan Rodgers has thus far succeeded in meeting the minimum requirements.He is certainly undeserving of an inflated status for remaining unbeaten against other Scottish teams who are of a similar status to Cork City or Dundalk (in fact no Scottish team came close to matching Dundalk's Europa League campaign this season).Given Celtic's huge budgetary advantage and wage bill,no Scottish team should be capable of even giving them a decent game.
He achieved every single objective this season and not even the most rose tinted of Celtic supporters would have predicted that the team would go unbeaten into the last week of April. If he achieves a treble it will have been an unbelievable season for Celtic supporters and the unbeated run is just the icing on the cake. The average attendeances tell you all you need to know. Rodgers does shoot his mouth off at times and has a bit of an ego but underneath it all I believe he is a good coach moreso than a manager. He has been good for Celtic and vice versa.
Since you brought budgets into it, Rangers budget for last year was over £10 million which is well in excess of the budget for the entire LOI so the comparision with Cork and Dundalk is daft. Dundalk in particular had some unbelievable results in Europe in a cup competition where anything can happen. It is unlikely to be ever repeated. However neither side would compete consistently at the top level in Scotland.
