West Ham United have announced the signing of Croatia international attacker Nikola Vlašić.

The talented 23-year-old arrives on five-year deal for an undisclosed fee from Russian Premier League club CSKA Moscow.

A teenage prodigy with Hajduk Split, Vlašić has already played more 250 senior matches, scored 33 goals and assisted 21 more for CSKA over the previous three seasons, and was named Russian Premier League Footballer of the Year in 2020.

A regular for Croatia, he has 26 senior caps and featured four times at the recent UEFA Euro 2020 finals, and will now continue his career at London Stadium after representing his country during the current international break.

The player has been extensively scouted and the creative attacker will add top-class quality and experience to David Moyes’ squad.

“I am delighted to welcome Nikola to West Ham United,” said the manager. "I have been watching Nikola improve over recent seasons – he has got a good goals and assists record during that time. He is also a Croatia international with experience and still being only 23, I feel there is more to come from him.

“I was really impressed with how determined Nikola was to become a West Ham player. It’s that hunger and ambition that fits with what we are trying to build here at the club.”

Born in Split in October 1997, Vlašić started his career with Omladinac Vranjic at the age of eight before moving to the city’s leading club, Hajduk, at 12 in 2010.

A teenage sensation, he scored on his first-team debut in a UEFA Europa League qualifying tie with Irish side Dundalk in July 2014, aged just 16 years and nine months. By the season’s end, he had made 37 appearances and scored four goals, still well short of his 18th birthday.

Vlašić made his senior Croatia debut at 19 in a May 2017, before establishing himself as a regular squad member the following year. He has since played 26 times in total, scoring six goals, including the opener in the Euro 2020 win over Scotland in June this year.

And he was still a teenager when he moved to the English Premier League side Everton in August 2017, having impressed Blues manager Ronald Koeman in a Europa League tie earlier that month.

After a single season at Goodison Park, where he featured 19 times, Vlašić signed for CSKA Moscow, initially on loan, and has been a major success in Russia.

In 108 games for CSKA in all competitions, he has been directly involved in 54 goals, won three Russian Player of the Month trophies and the 2020 Russian Footballer of the Year award.

Now, he will bring his considerable attacking talents to London Stadium.
