Former Chelsea striker Jimmy Floyd Hasselbaink has warned Timo Werner and Hakim Ziyech could initially struggle in the Premier League.
Frank Lampard's side have been on a major recruitment drive this summer, wrapping up deals for Werner, Ziyech and Thiago Silva with the club edging closer to a deal for Bayer Leverkusen star Kai Havertz that could take their spending to £200m.
Werner scored 34 goals in 45 appearances in a sublime final season at RB Leipzig but Hasselbaink believes the Germany international will need time to find his feet in the Premier League.
"German football is totally different to the English game so it will be difficult for Werner to settle straight in," Hasselbaink told GentingBet.
"We know he's a talented player. We know what he can do. And Chelsea need a player that can score goals. But, we also need to give him the time. If you look at Aubameyang when he came, he needed six months. So, give him those six months as well."
Similarly, Hasselbaink believes Ziyech will be a star at Stamford Bridge, but believes the physical demands of the Premier League mean he too will need time.
"Physically, he’ll possibly have a problem in the beginning, so he has to be smarter with his physical ability. But he is a silky, beautiful player and something that Chelsea don’t have – a midfielder with a left foot who can bring something different."
