Having announced that the talismanic Jamie Vardy will be unavailable due to an operationLeicester City's latest push for FA Cup glory continues with a trip to Brentford in the fourth round.

The Foxes faced the same opposition in last year's campaign, beating the Bees 1-0 in the last ever FA Cup game at Griffin Park.

While Leicester have been praised for their squad depth this season, the absence of Vardy will undoubtedly be a big blow as his goal scoring ability is unmatched at the club.

That being said, they have plenty of different options to choose from as they look to replace Vardy's goals.

Kelechi Iheanacho as a straight swap

The most obvious choice for Brendan Rodgers is to replace the Leicester number nine for another natural number nine in Kelechi Iheanacho.

This would mean that there is little change to the formation and the way that Leicester play, though Iheanacho offers more link up play and less running in behind than his counterpart.

The Nigerian has had mixed success this season, performing well in the Europa League with three goals and three assists in the group stage, while struggling in the Premier League, most notably with his penalty miss against Crystal Palace in a 1-1 draw.

The forward is still waiting for his first goal away from European competition this season but a good FA Cup record, including a goal scored against Brentford themselves last season, may lead to Rodgers backing him to kickstart his domestic campaign.

Ayoze Perez in a false nine

Due to the performances of the current first team, mixed with Ayoze Perez's preference to play more centrally, the Spaniard has not enjoyed as much game time as he had during his debut season with the club.

Recently however, Perez has seen match action more frequently and even started in the last round of the FA Cup upfront for the Foxes, something that Rodgers may elect to do again after a convincing display against Stoke City.

Perez played as a centre forward in that game, rather than a striker, meaning he allowed the wingers to push forward and play off him, utilising their pace as the Foxes attacked quickly as Liverpool do with the front three of Roberto FirminoSadio Mane and Mohamed Salah.

The former Newcastle United man also found the net playing in that position against Stoke, something that Rodgers will not have forgotten as he ponders over his team selection.

Harvey Barnes playing centrally 

Behind Vardy, Harvey Barnes has been Leicester's best goalscorer this season, notching 10 goals in all competitions, meaning that he too could be trusted to lead the line and score the important goals.

Rodgers has been vocal about Barnes improving on his quality in the final third and that has seemingly had an effect on the England forward as he is enjoying his best goalscoring season in a Foxes shirt with only half of the campaign completed.

Barnes offers pace in behind and quality with the ball at his feet, something on paper that he could transfer into the centre of the pitch, though Rodgers may be reluctant to take the winger away from the position that he has been thriving in all season.
