Silva signed for Milan in a €38 million (£33.6 million) deal in 2017, but after scoring 10 goals in his first season—only two of which came in 24 Serie A appearances—he was loaned to Sevilla last summer for this campaign.
The striker told Gazzetta dello Sport (h/t Football Italia):
"I want do well here first and then wait. If it was up to me, I'd go and play for the best team in the world.
"If they tell me to choose between playing as a starter at Sevilla or go back to Milan without playing, my preference is obvious.
"However I'm in the middle of two situations: I'm fine here and I'm a Milan player. I'm not thinking about my future, otherwise I get distracted."
Silva also said he has remained in contact with the Rossoneri and admitted he misses Italy.
"If Sevilla sign me then it's because they have faith me and think I can do well, but it's still too early," he added. "I haven't done anything yet. The present will ultimately impact on the future. I just want to play and be happy."
The Portugal international has already surpassed last season's goal tally having netted 11 times, with nine coming in La Liga.
ESPN's David Cartlidge believes Sevilla would be wise to make his stay in Spain permanent:
Silva likely feels he has unfinished business at the San Siro, but returning and commanding a starting berth there could be difficult.
The Pole had scored 19 goals in 21 matches for Genoa, and he has maintained that form since making his move last month:
Silva has so far been a strong acquisition for Sevilla, so it's likely he'll have the option of remaining there beyond this campaign if he continues to perform in the coming months.
A good season could tempt Milan into bringing him back into the fold, but unless they plan to use Piatek and Silva in the same system, he'd likely be playing second fiddle to the newer arrival.
