Liverpool will be far better equipped in that area with the returns of Gomez and Van Dijk as they join new recruits Ozan Kabak and Ben Davies as well as Joel Matip.
There is an £18m option to make the deal for Kabak permanent from German outfit Schalke.
Meanwhile, Solskjaer insists he is happy with the recruitment he has overseen at Old Trafford.
He said: “You know I can’t speak about Erling, he’s with Borussia Dortmund, it’s disrespectful to talk about it apart from that I know him and I speak to him.
“Who wasn’t interested in him a year ago? Everyone would say you take the best players in the world. Erling is a top player.
