Ex-Chelsea defender Graeme Le Saux was full of praise for the Blues after they sold goalkeeper Petr Cech to rivals Arsenal.
The Czech international left Stamford Bridge after 11 years at the club and Le Saux says Chelsea's decision to let him go shows how much they respect the goalkeeper.
"It was a very grown up thing for Chelsea to do. It shows the huge respect they have for Petr," the Englishman told Sky Sports News HQ.
"He still has a massive amount to offer and they were willing in the end to sell him to one of their main rivals.
"So that's Chelsea repaying his loyalty to the club as he was the best keeper in the Premier League, if not in the world, for a long period.
"He's a fantastic ambassador for the sport as well and he’s still got a lot to offer, so he’s a great signing for Arsenal too.
"He’s in a key position for them. Arsenal have strengthened their squad, still have a few positions to fill, but are title challengers."
