Chelsea captain John Terry accepts goalkeeper Petr Cech will be sorely missed when he leaves Stamford Bridge, as expected, and believes he is worth up to 15 points a season for Arsenal, who have reportedly paid £11million for the veteran, although there has been no official confirmation of a done deal.
Paris Saint-Germain formally approached Chelsea about the veteran but the Czech Republic international preferred to stay in London where his family are based.
Cech - who played an instrumental role in Chelsea's success since joining from Rennes in 2004 - may have found himself now as understudy to Thibaut Courtois at Stamford Bridge, but Terry is in no doubt of just what an important player the 33-year-old can be.
In an interview in China, where the former England defender is on a promotional tour, Terry said: "I am sure if he does leave the club, which nobody wants to see, but we understand he wants to play football, he is going to be sorely missed. He will improve whatever side he goes to."
Terry added: "There is obviously talk of Arsenal signing Petr and if they do get Pete, that will strengthen them for sure. He will save them 12 to 15 points a season."
Chelsea are expected to improve their own squad again for next season. A season long loan deal with Monaco for Colombia forward Radamel Falcao is expected to be completed after Manchester United opted against making the striker's temporary move permanent at the end of the season.
Terry believes Chelsea cannot afford to stand still if they are to stay ahead of the chasing pack in 2015/2016.
"To be top of the league the whole way through the season was an exceptional thing to do, but you can't kind of dwell on that. We have to start concentrating on next season and try to improve on that again," Terry said. "When you win the league, you know teams go and spend money to buy the best.
"Manchester City were a little way off this year and will strengthen. I feel Arsenal and Manchester United are going to be very strong as well.
"We all know once you win it, everyone wants to beat you the following year, (so) it will be even harder for us to win the league again."
Meanwhile, Ruben Loftus-Cheek has taken Jose Mourinho's recent criticism on-board and vowed to put in the work required to establish himself at Chelsea.
Loftus-Cheek has impressed since being brought into the senior set-up earlier this year, making four first-team appearances for the club he has been with since Under-8s level.
However, Mourinho claimed their relationship had taken "one step back" after a lackadaisical performance in a post-season friendly against Sydney FC which saw him hooked after just 27 minutes. It was a cutting assessment but one which teenager Loftus-Cheek finds hard to disagree with.
"I listened to what the manager said and I wasn't at the level. I need to do better if I want to play for Chelsea," the 19-year-old said.
"For me, that is a reminder that I have to work hard to get in the team. I just need to do my best, work hard and do my best."
Asked if Mourinho can make him a great player, Loftus-Cheek said: "Yeah, I will listen to him and learn from him every way I can. I really want to work hard now.
"Hopefully I just need to have a good pre-season. I want to work really hard. Chelsea is always hard to break into, but I believe in myself and if I work hard then hopefully things will go well."
