Seems to be a polarising topic that there might be an active thread on a high profile player in the football forum section of a massive internet message board. A few things maybe to take into consideration - it's not only been about him at Liverpool, there were about 50-60 pages of messages about him when he was still at Leverkusen. Also, despite all the snarky messages about "Utd fans making fun of Wirtz lol", the main contributors to this thread aren't Utd fans. When you look at the top posters in here, the top 10 ones aren't Utd fans - they're German or Liverpool fans. So let's take the number of posts with a pinch of salt as well.
Also, number of "chances created" is a bit of a silly stat. I think if you really want to judge the creativity of a player, looking at "big chances created" is a much better indicator - and in that ranking, he falls to 71st in the league, in the illustrious company of Dalot, Guéhi-playmaker-extraordinaire or Neko Williams.
Pretending that this transfer and his season have been anything else than an unmitigated failure at this stage is plain nonsense. He has puffed up his stats against mediocre opposition to make them look ok, but as soon as he's up against decent opposition, it's pretty bad. Beyond not impacting big games, he actively goes missing in them. He's shy, weak and doesn't seem up to it.
Now that may change (I've consistenly said that I think he'll be better in his second season in England) and I guess a change of manager, a fresh start after the summer, whatever, might be exactly what he needs to confirm his potential, but currently he's shown nothing in England and it's a bit tiring that Utd fans have to justify on a Utd forum why they're playfully mocking (I don't believe there's anything particularly egregious in the way he's talked about on here) a guy who was plain terrible in the last game against Manchester United.
