David de Gea and Dean Henderson are both vying for places in the United team and the Red Devils boss is happy to have two quality options to choose from.
Solskjaer said: "I've got two very, very good options and whoever plays will play well I'm sure.
"I cannot prioritise league or Europa League - every game here is the most important one. The next one is the most important one.
"Every time I try to explain to players why they don't play in this particular game, what they need to do and what my plans are with them - all those discussions remain private of course.
"David's been a top, top keeper and he still is a top, top keeper. He's working to be ready when he plays.
"If it's Dean, David, I'm very comfortable with both of them to play and I'm very happy that none of them are happy to not play."
Solskjaer also suggested that he would manage Marcus Rashford's fitness carefully as he doesn't want to "overplay" the striker.
He said: "I don't pick players when I know there's a risk.
"Of course, there's always a risk when you play football, but if the physios say 'this is too much of a risk', then I'll never play a player if we know in advance it's going to make it worse or be a serious one.
"Marcus joined in training this morning, so let's see how he reacts. If there's any risk of making this worse, I'm not going to overplay him.
"His back has recovered, but he's a tough one and he wants to play. He wants to give his all for Manchester United."
