Villa have just brought in a highly rated young midfielder from Norwich - Emiliano Buendía. Cost them around £33 million plus £5 million add ons.
Villa owners have a lot of ££ and don’t really need to sell anyone. McGinn is now good mates with Grealish and they enjoy playing together.
Liverpool though are looking to add more to the midfield especially after losing Wijnaldum who is a much better player than McGinn.
I don’t think McGinn will stay at Villa forever but I think he will stay another season at least alongside Grealish - but then can’t see them both leaving at same time as Villa fans would be going mad 2 of their favourite players leave the club.
