Terry served the last game of his domestic four-match ban for racially abusing QPR defender Anton Ferdinand as Chelsea drew 1-1 with Swansea, surrendering their position at the top of the Premier League at the end of a week dominated by the Mark Clattenburg affair.
Di Matteo, who is also hopeful of having Juan Mata and David Luiz back from injury, said: "He (Terry) is an important player for us and we will welcome him back, we will have to see how the next three days go and then we will make a decision."
The Blues have shipped 10 goals in Terry's absence, but while Di Matteo acknowledged his side have missed the former England international, he has yet to decide whether to return him to the side against the Ukrainian side in midweek.
On Mata and Luiz he added: "It is going to be a question of waiting for the next couple of days for them to recover and we hope they will be available to play."
Chelsea's goal at the Liberty Stadium came courtesy of Victor Moses, the former Wigan man's first league strike for his new club.
The 21-year-old was among Chelsea's best performers in south Wales, with his pace and trickery proving a constant thorn in the side to Swansea.
And Di Matteo is pleased by the development the Nigeria international is showing.
He said: "He has been doing very well, every time he has played he has performed well. He is still very young but there is a lot more to come from him and I was pleased with him.
"He is a big threat, he has tricks and pace and is becoming more effective when he finds space."
