Long and Clasie should have been introduced with Tadic kept on imo. His substitutions have always been bad from what I remember. He's really doing my head in at the moment though, because he can't afford to do it with how we've been playing.
Oh look who scored, Romeu! We deserved that and Koeman's changes have had a positive effect, let's give him some credit.
Amazing I still don't think it was a logical change. Luck rather than good judgement. Similar in a way to the Gibbs substitution change and goal from Arsenal against Spurs.
