United struggled to land their top targets in the summer, with Jadon Sancho remaining at Borussia Dortmund as United failed to meet BVB's £108million asking price.
But, after United latest financial figures showed a drop in income of almost 20 per cent during the pandemic, Solskjaer does not expect a busy window in January.
"It's hard to predict how other teams (will act) and how the financial situation is," he said. "If teams need to sell or if they've got money to buy. I don't predict a lot of ins and outs, to be fair.
"The world, financially, and in football, has changed as well also. It depends how the injury situations are at different teams.
"I feel very happy with my squad at the moment. We're getting stronger. I still have issues every week when we only get an 18-man squad to pick from. Who do you leave out? I feel I'm in a good position."
