The Dutch tactician was quoted as saying the following (via Sport Nieuws):"That is painful. That is the most beautiful competition, but the Premier League makes up for a lot. I will now watch Ajax on the evenings of the Champions League, as a big supporter."According to the Guardian, Erik ten Hag will arrive in Manchester on Monday, 16 May as he prepares to take charge of the club. Despite his arrival, Ralf Rangnick will still be in charge of the first-team on the final day of the season when they take on Crystal Palace on 22 May.Man United News@ManUtdMENErik ten Hag makes brutal admission about Manchester United and the Champions League #MUFC manchestereveningnews.co.uk/sport/football…18614Erik ten Hag makes brutal admission about Manchester United and the Champions League #MUFC manchestereveningnews.co.uk/sport/football…Manchester United have not enjoyed their best season this time around.

United, however, could find it difficult to attract a higher caliber of players as they do not have Champions League football at their disposal.
