It's common for a son to follow in his father's footsteps... and professional football isn't an exception to the rule.
Over the years, we've seen the likes Alex Bruce, Jack Cork, Shaun Wright-Phillips, Tom Ince, Kasper Schmeichel and Erling Haaland all emulate their dads by playing in the Premier League - with the latter bagging a hat-trick for Manchester City on Saturday.
But we don't often see many sons of famous footballers all thrust together in the same academy at the same time. That's the case over at Liverpool's Kirby training ground, where there are five youngsters with well-known dads currently forcing their way through the Merseyside's club's youth system. Here, Mirror Football profiles those players and their accomplished fathers.
Bobby Clark
It was a special afternoon for Clark on Saturday as he made his Premier League debut for the Reds, replacing Trent Alexander-Arnold in the second half. The 17-year-old forward is highly rated at Anfield, joining the club's academy from Newcastle 12 months ago.
"No feeling quite like this one making my Premier League debut in front of the best fans in the world at Anfield," tweeted the England youth international. "Dreams do come true."
Discussing Clark's progress earlier in the week, Klopp said: "I’m really, really happy with the boys Stefan [Bajcetic, who also made his debut on Saturday] and Bobby. I’m not sure they would be that close to the first team already at 17 years old if we would have them all [the whole squad] available, and then now they make real steps."
Clark's dad is former Premier League midfielder Lee, who represented Newcastle, Sunderland and Fulham. He's moved into management since retiring, enjoying spells at Huddersfield, Birmingham City, Blackpool and Kilmarnock before coaching overseas.
Remarkably, Lee played alongside current Liverpool midfielder James Milner during their time together at Newcastle. Almost 17 years ago to the day, Lee and Milner came off the bench in a Premier League game against Bolton, when Bobby was just six months old.

Keyrol Figueroa
The 15-year-old forward joined Liverpool's academy as an U14 player and will feature for the U18s as a first-year scholar this season. He's "blessed with great pace" and "is capable of scoring spectacular goals" - according to Liverpool's official website.
Premier League fans will remember his dad Maynor, who represented Wigan and Hull - playing more than 200 games in England's top-flight. The 39-year-old hung up his boots last year after spells in the the MLS with Colorado Rapids, FC Dallas and Houston Dynamo.
Maynor won the FA Cup with Wigan in 2013 - famously defeating Man City 1-0 in the final - and once scored a cheeky free kick from inside his own half against Stoke in December 2009. It was later named as the Goal of the Season by Match of the Day.
Lewis Koumas
The 16-year-old midfielder arrived at Liverpool's academy as an U11 player and has already represented the U18s. He's capable of playing on the wing - although his primary position is in the centre - and has previously played for fellow Merseyside club Tranmere.
Koumas' dad is Jason, the former Premier League playmaker who won 34 senior caps for Wales. Born in Wrexham, a town near Liverpool, the 42-year-old came through the ranks at Tranmere and made his debut in the First Division, now called the Championship.
Jason finished his career at Tranmere in 2015 after spells in the Premier League with West Brom and Wigan. He also played for Cardiff.
Prince Kobe Cisse
The 14-year-old forward is currently on the books at Liverpool and has represented Wales at U16 level, scoring and providing an assist in his most recent appearance last month.
Cisse's father is Liverpool cult hero Djibril, who last played professional football in 2015. The 41-year-old won 41 senior caps for France during his prime and represented the likes of Marseille, Sunderland, Panathinaikos, Lazio and Queens Park Rangers.
Djibril is best remembered for coming off the bench during Liverpool's 2005 Champions League final victory against AC Milan, helping them recover from three goals down to win on penalties. Cisse scored Liverpool's second spot kick in the shootout.
Jayden Danns
The 16-year-old forward has been on Liverpool's books since he was eight and is looking promising, making his U18 debut ahead of schedule last season. Danns is the son of veteran midfielder Neil, who was born in Liverpool and supported the club as a youngster.
Danns is best known for his long career in the EFL, representing the likes of Birmingham City, Crystal Palace, Leicester, Bolton and Bury. He currently plays for Robbie Savage's Macclesfield and Guyana at international level, as well as doing some coaching at Liverpool
Speaking exclusively to Mirror Football in April, Danns said: "Just working with the talent and seeing the next generation that's coming through is unbelievable. It's a completely different academy system to when I was coming through... it's more detailed.
"It's like relearning because it's been a long time since I was at that age. My son also plays for Liverpool. He turned 16 this year and he goes in full time at the end of this school year, so just being around to help him and all that sort of stuff has been brilliant."
