Liverpool is actually prioritizing the signing of Ekitiké these days. Newcastle was also after him but they have withdrawn from the race. Because his first choice is Liverpool now. They are only trying to make an offer which Frankfurt can accept.
Let's say this deal is off then I believe Liverpool will do their best to have an agreement with Isak. Either one of them would be a great choice for Liverpool.

They will finally have a more useful CF than Nunez.
Yes Liverpool actually moved towards Ekitike because they saw that the deal for Isak wouldn’t actually move through as Newcastle were already saying he isn’t for sale and any push from Liverpool will definitely mean that they will be paying more. This Ekitike was also Newcastle target as many thinks if Isak moves the other way he would be a replacement but seem Newcastle will rather have their own player than exchanging at this moment.
Ekitike is actually a good player and has similarities in terms of play like Isak but my only problem is that he hasn’t shown most of this for a long time like Isak and also the pressure of playing in the premier league, but for a price above €100m again for a Bundesliga player yet again I will say it is a gamble way too much and I will say Liverpool should explore the possibility of getting this Isak instead
I saw the rumors of Jackson being offered to Manchester United and I found it funny because a few weeks ago Manchester United fans were trolling Arsenal for having an interest in Jackson. Getting a striker has always been a difficult task for clubs and in this market there are just a few left to go; Vlahovic, Sesko, Jackson, Calvin Lewis.
It’s not a new thing, many players have in the past be offered to Manchester United not to talk of those Manchester United have also shown interest in but in the end it didn’t materialize. For me Manchester United are slow in transfers this year again but they are seriously doing it more better this time around, I doubt with options they have they will go for Jackson at the moment
