Two former Premier League champions will go head-to-head on Sunday in the FA Cup's Fifth Round as Blackburn Rovers host Jose Mourinho's Manchester United.

Rovers famously won the title in 1994-1995, as Alan Shearer and co. pipped United to first place in what was - up until last season with Leicester City - the most unlikely of Premier League title wins.

United, meanwhile, have won the First Division title a whopping 20 times, their most recent one coming in 2012-2013 during Sir Alex Ferguson's last season in charge.

That year seems a distant cry away from where United currently sit, with the club having struggled for such dominance in recent seasons under David Moyes, Louis Van Gaal and now Jose Mourinho.

But United's downfall over the past few seasons bares minimal in comparison with Blackburn, who now reside in 23rd position in the Championship and look all but set for relegation to League 1.

While Owen Coyle's side's form has picked up slightly as of late, the club still look a poor outfit, and United fans will have been rubbing their hands at the chance to make it through to the FA Cup quarter-finals as they try to defend the trophy they won last season.

Bearing in mind the limited quality of the opposition, we take a look at three youngsters who deserve a chance to impress Mourinho vs Rovers.

Marcus Rashford

It seems odd talking about Marcus Rashford as if he is an up-and-coming youngster having seen his unbelievable breakthrough into the first team and England squad last year, but he's still some way off the finished article.

The 19-year-old has fallen down the pecking order under Jose Mourinho - whose reputation for excluding young players once again has followed him to Old Trafford - but still impressed when given the chance, looking as exciting as ever, albeit slightly less clinical.

He can be forgiven though as he's been utilised out wide for much of he campaign, a position he is not normally accustomed to. Keeping a starlet that could be the future of English football happy, fit and with game-time under his belt is important.

Axel Tuanzebe

Tipped by Louis Van Gaal last season to make a breakthrough but never given the opportunity, Tuanzebe actually got his chance under Jose Mourinho this term, as he played against Wigan in the previous round.

United won comfortably 4-0 and young Tuanzebe impressed with a commanding performance at the back, albeit against a weak Wigan Athletic attack. The DR Congo born defender has both the physical attributes - tall, strong, pacy - to succeed at United as well as the mental, with his reading the game being excellent for such a young player. His ability to lead sides is also something to admire, having captained the U-19s on multiple occasions.

Joel Castro Pereira

It may seem silly to drop your top shot-stopper, perhaps even the best in the world, but at some point United will start having to look the future, whether it be with David De Gea or without.

Joel Castro Pereira, like Tuanzebe, made his professional Red Devils debut against Wigan in the previous round of the completion, but was given little time to impress having come on as an 80th minute substitute for Sergio Romero.

The Portugal U-20 star was recalled from his loan spell at Belenenses after the departure of Sam Johnstone on loan to Aston Villa, and he impressed for the Primera Liga side, making nine appearances for the club.
