KIERAN TIERNEY is already hitting the heights at Arsenal – despite not even making his debut.
The £25million signing from Celtic has broken Pierre-Emerick Aubameyang‘s standing jump record.
And the full-back achieved the feat even though he is injured.
Tierney reached half a metre on his first attempt, and was then told by Arsenal’s medical team who held the record.
It was game on, and then Tierney incredibly reached 55cm – beating team-mate Aubamyang’s previous record by 1cm.
Rob Holding, himself on the way back from injury, looked shocked at Tierney’s feet.
A double hernia operation has ruled out the Scot for the start of the campaign.
On his first training session fellow full-back Hector Bellerin, who missed the last six months of last season through a cruciate ligament rupture, welcomed the new Arsenal defender.
TIERNEY OUT FOR SIX WEEKS
But Bellerin warned: “It’s Arsenal brother, the cameras follow you everywhere.”
The Spanish right-back even boasted about his left foot, after being accused of trying to take Tierney’s No3 jersey.
Tierney is ruled out for up to six weeks with the Gunners hoping to introduce the defender to full training half way through that period.
The £25m signing revealed he was practising down the park with his friends when he found out his move to Arsenal was given the greenlight.
Tierney said: “I got told at seven o’clock that I had to be at the airport in an hour, so I had to go quickly.
“I was actually down the park with my friends training. They play with their local team so I was down watching them and I got a phone call that I needed to go.
“I got to the airport and the flight was delayed two-and-a-half hours, with another hour’s drive for a hotel and I probably got zero sleep.”
