Within the space of 11 days, Bellerín has had three tricky tasks to contend with for Arsenal.

First, the relentless energy and eye-catching skills of Douglas Costa for Bayern Munich.

Then, the duo of Aaron Lennon and Kevin Mirallas for Everton – neither of which are particularly slow in any regard, and love to beat their marker accelerating down the wings.

Today, it was another tough battle down the right hand side, up against Jefferson Montero. The 26-year-old Ecuadorian has already previously tormented Arsenal, creating chances with seeming ease in both fixtures last term, and established himself as one of the Swans’ best players during the campaign.

What Héctor lacks in physicality, he makes up for it with both agility and impressive speed. For a full back in modern day football, most tend to attack rather than defend, but Bellerín has an encouraging balance of the two; not afraid to get forward on the counter-attack, but not reluctant to track back when his side are out of possession.

He highlighted this desire once more as his display helped keep a clean sheet in a tough away fixture.

Montero looked lively whenever he was on the ball, but soon realised it wouldn’t be particularly easy to rule the roost on the wing today.

Only on two occasions did Montero actually get the better of Bellerín. One resulted in a cross which was headed clear by Koscielny, the other was a late sliding tackle to break up play on the edge of the area as he attempted to cut inside.

Although the set-piece could have resulted in a real chance, it struck the wall and the danger was averted, meaning Swansea had to restart and try to restore momentum as the first half was almost finished.

Speaking of real chances, Bafetimbi Gomis had a great opportunity to break the deadlock after a defence-spliting pass by Jonjo Shelvey exploited the high line to devastating effect.

The experienced Frenchman dithered in possession as he advanced towards goal, and with Cech seemingly beaten, he lacked the composure required to open the scoring. Bellerín was alert to the impeding danger and sprinted back quickly to deny Gomis, with an excellently timed challenge, seeing the ball out of play within seconds to keep the scores level.

As the match continued, Arsenal naturally grew into it. The half time whistle was a relief for Arsène’s side, meaning they could have some brief respite and try to collectively improve on a frustrating 45 minutes as a whole.

They did just that, and Bellerín – in vain – made an excellent sliding challenge to clear the ball off the line before he collided with the far post 10 minutes into the second half as Swansea looked for a goal of their own after Giroud’s opener just minutes after the restart.

It was the epitome of his overall performance, putting his body on the line for the team, doing anything and everything necessary to ensure Arsenal kept a clean sheet at the Liberty.

Thankfully he was okay to continue, and looked a threat attacking-wise as the Gunners began to turn the screw on their hosts in a clinical display.

His deliveries were constantly threatening and Swansea had to be alert at times, whilst he lessened the impact of Montero in the second half. Instead the ball was often being played towards the left hand side, where André Ayew always looked to try and create something out of nothing, despite Nacho Monreal’s efforts to thwart him too.

At only 20-years-old, Bellerín has already asserted his credentials as a mainstay in the Arsenal starting XI, and is one of the League’s best full backs too.

Experiences like these are certainly beneficial to his development, because you can see improvements consistently, which will undoubtedly help his confidence.
