It depends on what we think we need. Another defensive minded player or more of a playmaker. Imo we got enough creativity around the pitch: Pogba, Fernandes, Rashford, Greenwood from the front, Maguire & currently Lindelof from the back + Luke Shaw, they all have playmaking skills to get us chances we need, all we might need is steel and that bit of flair can be something extra but it is very hard to find that kind of player who have both.
Rice would be a good alternative to Fred but whoever thinks we will improve our creativity/ is insane, he's not even better than Fred and they are similar defensively. Perhaps they could work good in pair while McT is just average both defensively and even worse going forward. But imo wouldn't be that bad having Rice to form an ultra hardworking duo to provide that solid base, especially with dodgy passive defender like Lindelof but that's another topic we should address and new acquisiton there wouldn't make us compensate in midfield. Ole hopefully knows it judging how much time McFred spent together.
For me Rice is another overhyped young english player so much pushed by media to succeed it's incredible but profile wise I think we could do well with that kind of CM because we are one Fred injury away from losing all the protection and legs in midfield. Those who watch closely can easily identify the zombie games with Pogba/McT, Matic combos at CM, with the lack of protection and tempo so much needed at top flight football. In reality it's not a big problem with Rice himself but how much he's valued, if he'd cost 30million he would certainly be worth a punt and time spent developing but he'd more cost 60-70 million now which is crazy amount comparing that to his basic abilities.
As a b) plan it would certainly be tempting to land someone like Tielemans but then we might have that problem again with a player like Fred out, because Tielemans as we all know is not a slouch but he certainly can't work well without a monster defensive player like Ndidi. We could also save ourselves some crazy money and give Garner because he's similar profile to YT and would provide both good creativity form the deep but also decent amount of protection from what it seems. But it might be perhaps one season too early for him to feature regularly for a team like ours.
So we should just plan around what we have and will have soon because funds are not unlimited like at City.
