Surely it isn't a reliable source, since all reliable sources seem to indicating he will have to stay.
Both El Mundo Deportivo and Sport said today that we will have both Coutinho and Dembele in upcoming days.
For Coutinho, these papers say that he will come:
1. Either before Thursday
2. Or at the weekend
3. Either way, his transfer is more advanced than Dembele's and he will be our 2nd signing
Too many indications are saying that he will come.
Everything is possible, but my rough estimation based on similar transfers and similar storylines in the past is that he will be our player in the next 4-5 days.
We still don't have a single word or a hint from Coutinho where he says that he will stay in Liverpool.
That is an extremely important clue.
