John Terry is confident Gary Cahill will slip seamlessly into the Chelsea fold, with the Blues skipper looking forward to playing alongside a man he has seen plenty of while donning the colours of his country.
The 26-year-old England international arrives at Stamford Bridge in a reported £7million switch from Bolton, with the defender set to play a leading role in the club's present and future.
"First and foremost, he's a great player," Terry told Sky Sports News. "He's established himself in the England side in the last year, so that's great for the football club.
"He's a really solid defender, he can play left and right foot, he's great in air and is quick as well. He also scores a lot of important goals, which could be key for us over this campaign.
"The manager chops and changes players here and there, so we're expecting that. Whoever plays, we are just strengthening our squad and hopefully securing the future for Chelsea."
Andre Villas-Boas will be hoping that the addition of Cahill can help Chelsea to keep things tight at the back, having slipped 11 points behind table-topping Manchester City in the Barclays Premier League title race.
However, Terry insists that the players will not throw in the towel, and says it's down to the club's senior stars to make sure the winning mentality and desire for domestic success remains.
"We are quietly there," he added. "We need results to go our way obviously, but this weekend could be a really big weekend for us.
"Spurs go to City and its Man United-Arsenal, so if we can win our game at Norwich, which will be a really tough game for us, we will be creeping in there.
"When results don't go too well, it's the old guys who bring the team together and go again. The older players in the squad have got a lot to give and when we sign the likes of [Daniel] Sturridge and Cahill, they can learn and improve."
