Manchester United could reportedly make an approach for Alexander Isak if Cristiano Ronaldo leaves at the end of the season.
Ronaldo has netted 14 goals since his surprise comeback last summer, but he is reportedly frustrated with his situation.
The Portuguese returned with the aim of winning trophies, but the club are now fighting for the Premier League top four.
They could end up missing out on the Champions League next term. Ronaldo could push for an exit regardless of this.
United are prepared for such a situation, and Daily Mail claims that Isak could be a potential candidate to replace him.
Real Sociedad are willing to accept a much lesser sum this summer, but the Gunners could face strong competition for him.
