Ranking the 5 worst Premier League signings of the summer transfer window

Premier League clubs splashed cash like never before.

They spent more than £150 million on transfer deadline day alone, bringing the total summer figure to a record £1.165 billion, according to BBC Sport. That's an insane amount of money fuelled by ever-increasing television revenue and sponsorship deals, a domino effect that has allowed England's top 20 teams to offer luxuries many others around Europe cannot.

That also means mistakes are more expensive, and several signings are looking that way already.

Here are five players who won't live up to the price tag:

Simone Zaza - Juventus to West Ham

Initial €5-million loan fee, plus a €25-million buyout clause

West Ham tried and failed to sign a selection of top-tier strikers before settling on Simone Zaza. It was obviously the plan of co-chairmen David Sullivan and David Gold to give midfield maestro Dimitri Payet a suitable target man, but Zaza isn't it.

The Italy international is a modest goal scorer who added depth to Juventus last season. After all, his game-winner February against Napoli all but sealed the title for Bianconeri.

He just can't guarantee a return in the double digits.

Zaza is a hard-working player who doesn't always make the right decisions in front of goal - as evidence by his pantomime act in the Euro 2016 quarter-final shootout against Germany - and it's that kind of frustrating form that currently defines him.

Jordon Ibe - Liverpool to Bournemouth

Club-record £15-million fee

Last year, Jordon Ibe looked like an exciting replacement for Raheem Sterling. Brendan Rodgers clearly adored the player, and even loaned out Lazar Markovic before the start of the 2015-16 season to give Ibe playing time.

He made his Liverpool debut as a 17-year-old, and Rodgers utilised Ibe's speed on the right flank. But his performances became a frustrating spectacle, the talent only showing in flashes.

At 20 years old, Ibe could yet put his career back on track. One of the reasons why he joined Bournemouth was Eddie Howe, whose philosophy is similar to Rodgers' quick style of play.

But his first three games for the south coast side showed little, if any, improvement. He was particularly poor during a 1-0 loss to West Ham, missing a sitter and misdirecting crosses throughout the match. Paying a club-record fee for a player who may amount to nothing is a big risk.

Yannick Bolasie - Crystal Palace to Everton

Reported £25-million fee

On his day, Yannick Bolasie is one of the most electrifying players in the Premier League. His story is a good one, too, having climbed the football ladder in England from non-league to the top flight.

Bolasie has the ability to win matches on his own, but he's not a winger that scores many goals, banging in just nine over the past two seasons.

He's not worth anything near the £25-million fee Everton paid to get him, and Toffees supporters likely won't get the goals they crave.

Moussa Sissoko - Newcastle to Tottenham

Reported £30-million fee

Some of Europe's biggest clubs, including Juventus and Real Madrid, circled around Moussa Sissoko following his impressive exploits at the Euros. He was a creative presence for France on the right wing, although it was news to Newcastle United supporters.

The Magpies rarely witnessed the same dynamic, pacy player during the 2015-16 Premier League season. He couldn't produce a string of consistent performances, and the fans at St James' Park hurled invective at him.

It's clear Sissoko is at his best in a counterattacking role, when he is able to run at defenders and join the attack. He enjoyed a better time under Rafa Benitez, though the Spanish manager wasn't impressed with Sissoko's public push for a move.

Still, Tottenham just paid £30 million for a player who may not even start regularly for the club. He could give Mauricio Pochettino some tactical headaches, with the likes of Erik Lamela already cutting a mercurial figure.

Claudio Bravo - Barcelona to Manchester City

Initial €18 million, plus additional €2 million in add-ons

Pep Guardiola's obsession with sweeper-keepers led him to Claudio Bravo. The Chilean shot-stopper is clearly a temporary solution, with Geronimo Rulli waiting in the wings at Real Sociedad.

Guardiola dropped club legend Joe Hart in the process, an unpopular decision that could define the early part of his City legacy.

The Spanish gaffer admitted that Hart has done more for the club than he has, but it remains to be seen whether jettisoning England's No. 1 was the right long-term decision.

Bravo's qualities cannot be questioned. He's an excellent distributor of the ball, and that's exactly what Guardiola wants.

He has done this before - he famously shipped Samuel Eto'o and Ronaldinho out of Barcelona - but he's now opened himself up to criticism at such an early stage of his Premier League career.

City's previously been very careful with the players it has signed, selecting those who can be part of a sustainable project. Bravo is merely a stop-gap in a bigger plan - and an expensive one at 33 years old.
