Sunderland have completed the signing of Celtic right-back Adam Matthews for a fee of £2million.
Diego Poyet is determined to establish himself in Slaven Bilic's West Ham side this season and avoid another loan spell.
Having been deemed surplus to requirements by then boss Paolo Di Canio, Cattermole was expected to be ushered through the exits before the transfer window closed.
He was, however, to make it through to Gus Poyet’s appointment and enjoyed an upturn in fortune under a new management team.
Cattermole admits he is now enjoying his football again and is looking forward to the 2014/15 campaign after recharging his batteries.
He said in the Northern Echo: “I had a good break. I didn’t get that really last year because of the knee injury I ended the season with, so I was in Monday to Friday and the odd Saturday when the others lads were on holiday. I only had four or five days off.
“Then I came back and I wasn’t in the picture. I sat tight. A lot went on last year but this time around I feel great. I’ve had a good holiday, time away this time, and I have had a good pre-season under my belt.”
Cattermole is confident that Sunderland can avoid a repeat of their relegation struggles of 2013/14 when Premier League competition resumes, but admits a few more additions would not go amiss.
Patrick van Aanholt, Billy Jones, Costel Pantilimon and Jordi Gomez have already been added to the ranks, but their arrivals have helped to cover the loss of Jack Colback, Phil Bardsley and Craig Gardner.
Cattermole added: “As players we chat, we chat about the players being mentioned and what we think we might need.
“Everyone does who has an interest in Sunderland I’d imagine. We can’t affect any of that.
“If we end up going into the season with what we have now, then we have to make sure we are all pulling in the same direction.
“Lads might end up staying this year who were out on loan last time, they could have a big part to play. We have lost good players from last season as well, so we know we have to add.”
