Chong and Gomes were left out of United's squad for Thursday's Europa League round of 32 first leg at Club Brugge, with the pair instead playing a behind-closed-doors friendly against the Belgian side for a United development team.
Chong scored in a 2-0 victory for United and Solskjaer hopes he and Gomes can be convinced to commit their future to the club.
"We are still in talks with them," said Solskjaer. "Tahith scored [on Thursday], he'd rather play a game than sit in the stands here, so it's just about making sure he is ready when he gets a chance.
"He played really well against Wolves in the FA Cup; I was very pleased with him then. The boys have got top class attitude, they're top boys.
“We are doing what we can to keep them because in a few years we can see them becoming very, very good players."
