Wilson was loaned to Bournemouth in August and the rules of his move mean he is ineligible to face his parent club.
"Of course he can succeed - that's why we loaned him so he can make the steps," said Klopp.
"It would have been difficult for Harry and I would have loved to have had him here if we had another choice, especially when Shaq was injured. You want to have these kinds of players.
"But now is not the moment to decide. All the players we sent on loan have the chance to make it in the first team otherwise we would have sold them. His shooting is world class, that is how it is. Find me five players who shoot better than him, that is obvious.
"The game is more than that and that is what he has to improve and that is clear. But to be involved as an offensive player you have to connect with other players. He has that, it is not like he doesn't, but to get to the next level, he needs game-time at the highest level and that is why we loaned him."
