If this is what they've done, not only is it completely out of order, to try and further politicise an issue tha has led to a woman and her young child having to live in fear of their lives, but it is enormously counter productive.
I remember as a teenager I broke my foot playing for a team. As you can probably imagine, I was quite the gobby little you know what even back then, and used to organise whole team in almost a sweeper position. They lost the 1st game I was away 14-0 and I remember the manager politely saying to my parents I shouldn't come back and watch until I could play again. It was a distraction, and they needed to learn to find solutions without me being there, which over the time they did to be fair.
I think the near constant harking back to Van Dijk hasn't helped them in the least. At best it's likely to cause resentment from existing players and at worst it will cause them to feel enormous pressure that it's constantly being reminded to them they are not as good as Van Dijk. Plopping him in the stands won't help either. A bit like when Alex Ferguson was there under Moyes, it's just not helpful.
It will not go down well in a dressing room. Forget all this team spirit nonsense, there was a young Liverpool defender who said he deliberately tried to injure another player to get a game for the team, and this qas semi encouraged in their reserves or whatever. There was no sanction on him. Phillips will be delighted Van Dijk got injured, as it gives him exposure. It's a dog eat dog world. The referring back to him will not be helping, and if we are honest, it has caused their season to become derailed.
