Tottenham Hotspur manager Mauricio Pochettino will be keen to boost his squad this summer in order for them to once again challenge for the Premier League title, as well as trying to compete in the Champions League as they move to Wembley for one season.

Spurs have been known to promote and give young players such as Harry Kane, Dele Alli and Harry Winks a first team platform to perform on in recent years and it has proved to be a successful formula for the north London outfit.

Kane and Alli have thrived under the leadership of Pochettino – especially last season – and Tottenham may well be keeping a close eye on players currently performing at the European Under-21 Championships in Poland to find their next gem.

With the likes of Spain, Italy and Germany all competing, Spurs could find their next future star that could challenge for a spot in the starting line-up right away.

Here are three European Under-21 Championship stars Tottenham should sign…

Inaki Williams

With last summer’s arrivals Moussa Sissoko and Georges-Kevin N’Koudou failing to impress and Erik Lamela definitely being ruled out for the start of next season and Son Heung-Min a doubt too, Pochettino is sure to be looking for an attacking player this summer.

He could certainly do a lot worse than take a look at Williams, who usually features on the right wing but can also play on the opposite flank or as a centre-forward.

The Spaniard scored eight goals and provided a further eight assists for Athletic Bilbao last season and scored his first of the European Under-21 Championships on Tuesday as Spain beat Portugal 3-1 to reach the semi-finals of the competition.

Pacy, unpredictable and versatile, the 23-year-old could prove to be an excellent signing for Tottenham.

Marcus Ingvartsen

With Vincent Janssen another player that has failed to make a significant impact after joining Spurs last summer, Pochettino could look to sign another young player to provide competition and cover for Harry Kane next season.

The Argentine manager may well be keeping a close eye on Ingvartsen at the European Under-21 Championships with the striker scoring eight goals in just nine caps for Denmark at that level.

Having also netted 23 times for FC Nordsjaelland in his home nation last term despite being just 21 years of age, it only seems to be a matter of time before he moves on to bigger and better things, and he could certainly be an interesting option for Tottenham.

Niklas Stark

Tottenham have already been linked with moves for Manchester United’s Chris Smalling and Swansea City’s Alfie Mawson this summer, which suggests that Pochettino is in the market for a new centre-back.

If he is looking for a young player to provide competition for Jan Vertonghen and Toby Alderweireld with a view to replacing them in the long-term, he should be taking a closer look at Stark at the European Under-21 Championships.

The 22-year-old – who can also play in defensive midfield – made 32 appearances in all competitions for Bundesliga outfit Hertha Berlin last season and looks to have a bright future.

Tall, comfortable in possession and strong in the tackle, the German has many of the ingredients needed to be a success in the Premier League.
