Manchester United have reportedly identified Atletico Madrid defender Kieran Trippier as a potential future signing.
If United are able to cash in on one of those players, it would leave Solskjaer to target reinforcements in that area of the pitch.
According to The Telegraph, the Premier League giants may contemplate an approach for Trippier, who has starred for Atletico since his switch to Wanda Metropolitano last year.
The England international has made 48 appearances in all competitions, 15 of which have come in La Liga and the Champions League during the current campaign.
The 30-year-old has just 19 months remaining on his contract, putting Atletico in a position where they will have to consider negotiating fresh terms with the player.
