Unless Liverpool beat Sevilla in the Europa League Final next week, Anfield will go without Champions League football for another year. It what used to be a given at the ground, but Europe's premier club competition has become a rare event in the last few seasons, hampering the Merseysiders' movements in the transfer market.

There is a glimmer of hope for Reds fans, however, in the shape of Jurgen Klopp. The German will be able to bring in top class players, even if Liverpool cannot offer Champions League football next year, simply because he is one of the game's brightest coaches.

Players are going to relish the chance of performing under the charismatic former Dortmund chief as he goes about trying to restore the long gone glory days of the club. Next season will be one of hope for the Reds as they look to get back into the Champions League, and with a highly anticipated transfer window on the horizon, FootballFanCast brings you five players Liverpool need to sign to return to the top four...

Isco

Isco is a good player whose career is threatening to fizzle out.

The Spaniard turned 24 last month, but is not playing as much as he'd like, nor as much as he should be given his calibre. Real Madrid have a wealth of midfield talent at their disposal and, because of this, Isco is unlikely to play every game for the Spanish giants. If he wants to play week in, week out, it's time to move and he'd reach his potential under Klopp.

Mario Gotze

The uncertainty around Mario Gotze's feature is well documented.

The man that scored the winner in the World Cup Final against Argentina risks seeing his career pass him by when he should be going on to establish himself as one of the world's finest players. Whether he returns to Dortmund, tries to prove his worth at Bayern to incoming manager Carlo Ancelotti or moves away from Germany remains to be seen, but the draw of playing with Klopp again could prove to be too tempting to turn down.

Neven Subotic

Subotic has seen very little playing action this year in the Bundesliga for Dortmund and this has inevitably led to uncertainty over his future.

The Serbian was an integral part of Klopp's German champions and would likely jump at the chance to link up with him again, and could bolster a Liverpool defence that has been unconvincing at times this year.

Keylor Navas

A new goalkeeper is key to improving fortunes for Liverpool and they don't come much better than the man from Costa Rica.

Navas has excelled for Madrid this year after the threat of David de Gea joining abated last summer. That rumour is set to ignite once more though with Manchester United again struggling this year despite De Gea's heroics, and if Navas finds himself playing second fiddle to the Spaniard he's going to be pushing for a move. He's a great 'keeper and would stabilise Liverpool's back-line no end.

Alexandre Lacazette

Is this who West Ham LAC?

The French forward has had another stellar campaign for Lyon with 23 goals in 42 appearances.

Daniel Sturridge is Liverpool's only guaranteed source of goals, with Divock Origi having much to learn and Christian Benteke looking set to leave. Lacazette would boost the Reds' goal difference markedly, and at just 24 would be coming into his peak years at the right time for Klopp's men.
