Who is Blues record-breaker Walsh?

Reggie Walsh made his fourth senior appearance for Chelsea on Wednesday and manager Enzo Maresca thinks the midfielder is already special.

Having had an accomplished career in the position himself, the Italian has plucked this youngster out of Chelsea's academy - and his GCSE year at school - to allow him to become the club's third youngest ever player.

Walsh turned 17 on Monday and came on for Romeo Lavia in the 65th minute against Ajax on Wednesday, becoming the second youngest Englishman, behind only former Arsenal midfielder Jack Wilshere, to play in the Champions League.

Walsh has already broken a host of records:

• He was already Chelsea's youngest player to play in Europe when appearing at Djurgardens last season in the Conference League, aged 16 years and 193 days.

• He also became the club's third youngest player, behind only midfielder Ian Hamilton and goalkeeper Kingsley Whiffen - who made their debuts in 1967.

• One week later, he became the youngest player to start a European match for Chelsea when facing Djurgardens in the second leg.

• And he is also Chelsea's youngest player to play in the League Cup, having played against Lincoln in the third round last month aged 16 years and 338 days.

Such was the surprise that Walsh was called up into Chelsea's first team at the end of last season, his family had not anticipated him making his debut in Sweden.

Fortunately, they got to see him start one week later.

Walsh, a technical, deep-lying playmaker with a good engine and great vision, only signed his first professional contract on Monday.

He counts pundit and former Spurs and Liverpool midfielder Jamie Redknapp as a family friend and is also an England Under-18 international.

Still, it was surprising when Maresca plucked him from the under-18s - given he had made just two appearances for the under-21s when making his debut last season.

Maresca previously said "he makes everything [look so] easy", adding that he was "perfect" for "his system", and he showed just that against 10-man Ajax.

Walsh completed 18 of his 19 passes on Wednesday, with 16 of them being in Ajax's final third. He also won possession twice through two interceptions.

In short, Walsh is the chosen one by Maresca and could be next off the production line at Cobham.
