With Paolo currently in Italy after limping off against Southampton on Monday, Trevor says he is sorely missed.
"I am not quite sure of the exact situation with Paolo, but I hope it goes well for him as he is an integral part of the squad.
"You don't like to see anyone injured - let's hope he can recover as soon as possible."
As for the position at the bottom of the table, Trevor admits: "We all feel responsible because we are the ones going out there getting the bad results.
"It is down to all of us, the lads who are playing and the lads who are not playing, to keep on trying and giving 100% when we go out there."
And for Trevor, the added responsibility of helping out the younger players, if necessary, in the coming months.
The side features three players 21 or under week in, week out, and Trevor says: "They are strong characters, but I think at certain times the experienced lads like myself and others will bring that experience in hand, hopefully guide the players to the right decisions, and be able to give them a little bit of advice in certain areas."
As for the trip to Middlesbrough, he adds: "We are preparing as well as we can for the match against Middlesbrough, and it is a massive game again.
"Our away form has been encouraging this year compared to last, although we have had a couple of blips recently.
"But if we can try and get the performances as we did when we had the run of three games, then everyone will be happy."
And of the Southampton defeat, he says: "We went out there with a good game plan and didn't give them any time to settle on the ball.
"Really, we are pretty disappointed not to be going in at least one up at half time but anyone who was there could see everyone was trying.
"Unfortunately, we just don't seem to be getting the rub of the green at the moment.
"We had several clear cut chances in the first half but we just don't seem to be able to address that first goal.
"I felt we played well on Monday, especially in the first 60 minutes or so, though we lost a little bit of shape in the second half and Paolo was struggling with his knee.
"We were a little bit light in midfield when Paolo started to struggle, but up until then I felt we had the grip of the game - and were the ones more likely to score."
