As romantic as that sounds, I can't see it, for either party.
For us, even if he reduced his wages a good bit, or went to a games played based wage, he would still take up a foreign spot, and would attract that 'club legend is on the bench and you are not using him' attention. Can't see us going into a season with 3 strikers on the books, haven't done that in years.
And for him, as good as that sounds, it is a one year contract on potentially much lower wages. If a top level club offers him 2 or even 3 years at slightly lower wages than he's on, thats a better deal. And would he really want to be a backup guy. And would any of us truly like seing that?
Who knows, may well come to that, and it would be nice. But I do doubt it, I think he is off in a few months.
Edit. He has played 8 games this whole season. And that is without a goal scoring striker such as haaland or whoever we would sign. I know it is through injury and covid, but i don't see him playing 20 games This year, let alone next.
