Yannick Bolasie's horror injury sustained in a clash with Anthony Martial against Manchester United has more than likely ended his season.

In fact, as reported by BBC Sport, Ronald Koeman says the winger could be out for another 12 months. That's a massive setback for the attacker and Everton, who invested heavily in him last summer.

It leaves the Dutch manager with a big dilemma in this month's January transfer window. Does he spend big to ensure a quality replacement, even after splashing out on former Charlton Athletic youngster Adeloma Lookman?

Everton fans will of course want to see some money on the table, fearful that the club are not going forward under Koeman. Big names help appease those fears, so bringing in a fairly well-known player would certainly give the home support a boost.

With that in mind, here are FOUR big-name replacements for Yannick Bolasie that can make an impact at Goodison Park...

Memphis Depay

Memphis Depay has been struggling for games at Manchester United since the arrival of Jose Mourinho in the summer, but is still an intelligent and deadly winger on his day.

That makes him a great fit for a side like Everton, who can offer him first team football and the chance to prove he has what it takes to be a hit in the Premier League.

The attacker has only made one start for the Red Devils all season, in the EFL Cup, and even then found himself substituted after 55 minutes.

Mourinho clearly doesn't rate him but that's no disgrace with the likes of Marcus Rashford, Juan Mata and Anthony Martial all options for the Old Trafford side.

His dribbling ability and aptitude for a shot from distance would be valuable assets to Everton, and could provide a badly-needed cutting edge in the final third to compliment Romelu Lukaku.

Manolo Gabbiadini

While not an out-and-out winger, Napoli's Gabbiadini can certainly operate on the flanks. With Bolasie's injury, if Koeman can secure another quality forward, he might even favour playing both Lukaku and a player like Gabbiadini through the middle.

That would be an exciting prospect for Everton fans who have been somewhat frustrated with the lack of attacking ambition from Koeman's side so far this season.

The Napoli forward has Champions League experience this term but, like Depay, isn't getting as much game time as he would like.

He's scored four times in 18 appearances but has found the net in each of his last two games for the club. A move to the Premier League where attacking football reigns, and space is left for players like Gabbiadini to operate in, could be just the ticket.

Andriy Yarmolenko

Ukranian international Andriy Yarmolenko would be an exciting signing that could immediately make an impact on the right wing for Everton.

A ten-year veteran at Dynamo Kiev, it's the perfect time for the 27-year-old to seek a career in a bigger league, due to come into his absolute prime as a player.

That has never been more evident than in Kiev's recent stunning 6-0 victory over Turkish giants Besiktas. The winger scored once and assisted twice in a man of the match performance that ensured his side exited the competition with pride intact.

A regular for Ukraine, he's scored 29 goals in 67 appearances at international level and already has three goals in 2018 World Cup Qualifying.

Jesus Navas

Jesus Navas' contract is up in the summer and although he'd likely demand big wages, he could help Koeman's cause at Goodison massively, being both a big name and a player that is unlikely to require a large transfer fee.

The winger has been an effective option off the bench for Manchester City this season but hasn't been a regular starter under Pep Guardiola.

However, the former Sevilla man still offers plenty of pace and guile in the wide areas and has the ability to deliver a fantastic cross - very beneficial if you have the likes of Romelu Lukaku in the middle to stick the ball in the back of the net.
