I think Newcastle can be a serious competitor for Man United in the hunt for Kim Min-Jae because there are rumours that Newcastle has a big enough budget for next season. This can be a tough transfer because when there are 2 teams that are interested in the same player, it is likely that there will be a bidding war, and it can cause transfer values to be soaring.
In addition, there is also news that Sheikh Jassim made a fifth offer to the Glazers and there are indications that it is a final offer. So if the Glazer still counteracts the offer or remains silent, most likely that Sheikh Jassim will step down in acquiring Man United.
What is certain is that now Manchester United will have a fork in the road when it comes to recruiting this player because regardless of what you say, the budget will certainly determine in this case and Napoli which allows the release of Kim Min Jae will certainly look at the club with the biggest offer in this regard.
Manchester United need to try to compete hard when it comes to finances but on the other hand they have to try a different approach with Kim Min Jae and Napoli if they really want to sign this player.
