Ilkay Gundogan from Manchester City supports Timo Werner and Kai Havertz to shine at Chelsea

Manchester City midfielder Ilkay Gundogan has predicted that Chelsea newcomers Timo Werner and Kai Havertz will prove themselves in the Premier League.

Chelsea have yet to see the best German internationals since spending £ 142million on the Bundesliga pair last summer and compatriot Gundogan believes their gradual adjustment to the Premier League is “normal”.

Speaking of Chelsea ahead of City’s trip to Stamford Bridge on Sunday, Gundogan told Sky Sports: “They have two new German players who have tried to adapt as best they can.

“In general, I think it is not easy to adapt to the Premier League quickly when you are from another country. Given the current situation, I think it’s only more difficult.

“I think it’s normal for them to have a bit of problems, but they both have incredible talent and I’m sure they can both prove it in this league.”

Werner was second to FC Bayern Munich’s Robert Lewandowski when the strong striker scored 28 goals for RB Leipzig last season.

Despite this impressive record, the 24-year-old has only scored four Premier League goals so far this season after signing a £ 175,000-a-week deal for £ 53million in July.

Havertz, who came on for around £ 71 million, was considered the best prospect in the German top division at Bayer Leverkusen, but has only played three of Chelsea’s last seven Premier League games.

The 21-year-old playmaker has not been directly involved in a goal in any of his last nine league games and has spent three months without support.

Gundogan believes that Blues boss Frank Lampard used his extensive financial resources wisely in the closing season and built a squad that will fight for the title.

He said: ‘Like every year, Chelsea have a great squad with incredible players.

‘They got some really talented young recruits over the summer, spent a lot of money and some really good players so I think they will do well.

“They are also a team that has problems like everyone else, but they have a lot of quality and it will be a great game on Sunday.”
