Gautam Gambhir can't keep calm, hurls expletive from Lord's balcony after Washington Sundar castles Joe Root

Gautam Gambhir could not hold back his emotions after Washington Sundar provided the much-needed breakthrough by dismissing Joe Root.

Gautam Gambhir has usually shied away from expressing himself publicly ever since he became Team India's head coach. Unlike his conduct as a broadcaster, where Gambhir would have a go at almost everything under the sun and wouldn't mince words, the former India batter has mostly remained calm whenever he is watching his team perform from the dressing room. Barring a couple of instances, once during the Sri Lanka T20Is last year and recently during the Border-Gavaskar Trophy when India avoided the follow-on in the Melbourne Test, Gambhir has remained calm and composed.

Gautam Gambhir could not hold back his emotions after Washington Sundar provided the much-needed breakthrough

However, the coach was anything but that on Sunday. Gambhir, a two-time World Cup winner for India, could not hold back his emotions after Washington Sundar provided the much-needed breakthrough to the side in the second session of Day 4 of the Lord's Test against England. Sundar castled Joe Root around his legs, and the ace batter had to walk back after scoring 40 runs. Once the former England captain was dismissed, Gambhir couldn't hold back his excitement as he hurled a mouthful from the Lord's Cricket Ground's balcony.

Gambhir's reaction isn't surprising, as Root had earlier survived a close call after on-field official Paul Reiffel didn't raise his finger when he was wrapped on the pads by a Mohammed Siraj delivery. India went for a review, but the replays showed it to be the umpire's call.

Root scored a century in the first innings, and he was key to England posting a challenging target in front of India. However, Sundar provided the much-needed breakthrough to India, and Gambhir was just not able to hold back his excitement.

On the fourth ball of the 43rd over, Sundar cleaned up Root as he broke the partnership for the fifth wicket between the former England captain and Stokes. The World No.2 batter in Tests was bowled behind his legs.

The ball drifted in and sneaked past Root's bat to clatter into the leg-stump. Root lasted 96 balls at the crease, scoring 40 runs, including 1 four.

Watch the clipe below:

Minutes later, Washington Sundar got his second wicket as he rattled the stumps of yet another in-form batter, Jamie Smith. England's wicketkeeper walked back to the hut after scoring 8 runs off 14 balls.

Lord's Test going down to the wire

The Lord's Test between England and India is going down to the wire, and nothing much separates the two teams. Both sides posted 387 runs in the first innings, and heading into the final day, India need 135 more runs to win while England are 6 wickets away from victory.

On Day 4, India gained the advantage after gaining four wickets in the morning session. Joe Root and Ben Stokes then put on more than 50 runs for the fifth wicket. However, Sundar brought India back into the contest as he dismissed Root and Jamie Smith.

The Anderson-Tendulkar Trophy currently stands level at 1-1, and a thrilling final day is on the cards in the Lord's Test.
