The 20-year-old Norwegian has been excellent for Genk in the Belgian league and the Europa League too.
Tottenham have had their issues with midfielders this season as Mousa Dembele and Victor Wanyama seem to be injured throughout the year.
We have been stretched this season additionally with Eric Dier and Christian Eriksen picking up problems too, and it would make sense for us to sign a quality midfielder for the coming season.
The 20-year-old has the potential to get better and working with Mauricio Pochettino will certainly help him achieve that.
Tottenham were the only club in the Premier League not to sign players at the start of the season, and that cannot go on when the next campaign starts.
Poch has done a magnificent job this time as we have made our best ever start to a Premier League campaign, but we cannot stick with the same set of players at the start of next season.
Oliver Skipp and Kyle Walker-Peters have done well when given chances, but there have to be some changes in the squad soon.
