How will Scottish clubs respond to Euro disappointments?

Until Tuesday, champions Celtic's season was ambling along well. Three domestic wins without conceding and a 3-0 victory over LASK in the first leg of the Champions League play-off had them in good stead.Their position improved further with the opening goal in the second leg in Austria. Four LASK goals later, it was extra time. And then, the tie was lost as a fifth concession on the night consigned Celtic to the Europa League.They will face Benfica, Bestikas, Celta Vigo, Ferencvaros, Marseille, Omonia, Torreense and Union SG in the autumn but, before then, they have domestic matters to turn to, starting with a home match with Falkirk on Saturday (15:00 BST).Celtic's form pre-Austria and their record of five wins out of five against Falkirk last season would suggest this game should hold no fears for them but could a European hangover beset the Premiership holders?Captain Callum McGregor said they were "passive" and looked "scared" against the Austrian champions. Indeed, the way in which the tie got away from Celtic was alarming. Martin O'Neill side played 120 minutes during the week while Falkirk are refreshed after two weeks without a game. Despite that, John McGlynn's side await a first league win this season and face an almighty task to get one in Glasgow.Dundee were one of the teams Celtic beat earlier in the season, but narrowly.Since then, in the Premiership, Steven Pressley's side have taken big strides with 2-0 wins over Aberdeen at home and away to city rivals Dundee United, though a cup loss to Aberdeen was sandwiched in between.St Mirren are the only team other than Celtic with a 100% record in the league so far after two wins out of two against Falkirk away and St Johnstone at home. The Buddies sustained a heavy loss in their League Cup tie away to Rangers, ending their hopes of defending that trophy.Both Dundee and St Mirren should be refreshed after no midweek action, with the latter having had last weekend off too.And, on Sunday at 15:00, they host Hibernian and Motherwell, respectively - two sides coming off midweek European exits.Motherwell were already up against it away to Freiburg, who completed a 7-2 aggregate win to progress in the Conference League but Hibs endured a painful play-off exit at the hands of Gent, losing 3-2 after the Belgians scored two late goals.It may be a good time for Dundee and St Mirren to be meeting these teams.
