The arrival of several superstars at Chelsea this summer has heralded an exciting new dawn for the club. After securing a Champions League spot last season despite a transfer ban, Frank Lampard has now been backed through the most remarkable of spending sprees.
The likes of Kai Havertz, Timo Werner, Hakim Ziyech and Ben Chilwell have been signed for hefty fees, and there is no doubt that the expectation is for Chelsea to push on all fronts next campaign in the hunt for silverware. Thiago Silva and Malang Sarr have also been recruited on free transfers
But the players largely responsible for the west London outfit's exploits before the summer may now find themselves shunted to the sidelines. In the absence of any new faces, it was a number of academy graduates who led from the fore and helped fuel a young and impressive team.

Reports suggesting Mount is unhappy with the club's spending spree were torn apart
Tammy Abraham netted 15 Premier League goals, Mason Mount played the third-highest amount of league minutes of any Chelsea player and Callum Hudson-Odoi attracted fierce interest from Bayern Munich.
But now the talented trio will likely be forced to scrap harder than before for a regular first-team berth.
Here, Sportsmail takes a look at who will be glancing nervously over their shoulder ahead of Lampard's enviable team selection headache.

Kai Havertz was snapped up from Bayer Leverkusen and will undoubtedly hold a starring role
Abraham's impressive league haul last season saw him rank 12th among the top scorers and cemented his spot as one of the most prolific young strikers in Europe. But Werner's signing from RB Leipzig now poses an interesting conundrum for the Chelsea coaching staff to tackle.
It is the Germany international who will undoubtably become the first-choice frontman, although Abraham should provide stern competition.
The 22-year-old appears to be relishing the new-found battle to ensure he remains as high up in the pecking order as possible.

He told The Times: 'It is Chelsea Football Club. There are always going to be new signings. I don't do too well when I'm in my comfort zone. It's good to have me on edge. That's how I love to be.'
Abraham also alluded to wanting to start alongside Werner, but Lampard's preference for formations with just one man leading the line means he will likely start the new campaign on the bench.
The English ace is still young and raw and should not be overly concerned with Chelsea competing across multiple fronts. His time will come, and it will be down to him to snatch it with both hands.
According to Bild, Mount has not been best pleased with Havertz's arrival at Chelsea. The playmaker's signing from Bayer Leverkusen means that Mount, who also operates in an attacking role, is another academy graduate in danger of dropping out the team.
His father has laughed off the speculation, however, and Mount himself has also underlined his sheer will to fend off competition and remain a key performer under Lampard next season.
Mount exclusively told Sportsmail in January how he planned to deal with big-money additions and the challenge to avoid becoming merely a sporadic bench option.

'You just have to fight,' he said. 'You know Chelsea can always buy £60m or £70m or £80m players that are world class. They want to come here and take my place.
'Just because I am an academy boy and young, that doesn't mean anything. But the mentality I have means I won't be pushed over easily. I will fight for my position and keep working hard.'
The 21-year-old played 53 games across all competitions last season and rapidly became a fan favourite. His versatility across the front line means that he too will feature heavily next term, although Havertz is certain to take up his spot in the starting XI.
Exciting Chelsea prodigy Gilmour was named the club's academy player of the season last month. He had been handed his senior debut against Sheffield United and went on to make 11 appearances in total, two of which came in man-of-the-match performances in wins over Liverpool and Everton.
But his flying start to life in Chelsea's first team was brought to an abrupt end after a serious knee injury. The setback required surgery and Gilmour is not expected to return to action until later this year. The Scot is expected to be ruled out for three or four months, and his last cameo came back in July.
It is this lengthy absence, combined with the new signings, that could cause concern over his immediate future.

He will need to sharpen up after his recovery during the period in which the likes of Havertz and Ziyech will have embedded themselves into the team.
