Chelsea manager Frank Lampard is delighted with the additions of Timo Werner and Hakim Ziyech for next season.
Lampard believes they can make a big impact in west London and improve the level of their new team-mates.
“Having been in a transfer ban it made those two signings so important," he said.
“I remember as a player, when the club were bringing players here of a really high level, you would feel the excitement in training, feel the level of training rise at times when the players here would improve alongside the injection of quality."
