Jorge Sampaoli is by no means the tallest boss at just 5ft 7in but the Argentine is making a big name for himself.
The Sevilla boss is currently favourite for the Barcelona job and one of the hottest managerial properties in the game.
But he was cut down to size here with this defeat at Leicester, who are 15th in the Premier League.
Sampaoli, who turned 57 on Monday, has been highly regarded in Latin football for some time.
His impressive work as Chile manager from 2012-2016, when they won the Copa America twice, earned him a move to Spain last year.
After taking charge last summer, he has steered Sevilla to third in La Liga, where they have been competing with Real Madrid and Barca for the title this term.
Sampaoli was also dreaming of a first ever Champions League triumph for Sevilla but that dream died here in Leicester.
It should never have come to this after Sevilla battered Leicester last month at the Ramón Sánchez Pizjuán Stadium, where they missed a penalty and hit the woodwork twice.
But Jamie Vardy’s late goal in the first leg gave the Foxes hope and shocked the visitors here.
Sevilla were highly competitive and Sampaoli helped set the tone himself on the touchline with an animated display.
He was very active as he raised his hands to the heavens theatrically when Kasper Schmeichel denied Samir Nasri early on.
He got out of his technical area to try to organise his defence when under pressure at set-pieces.
And he paced up and down the touchline like a man possessed in the first half.
His mood wasn’t help by seeing his side fall behind to Wes Morgan’s opener from a set-piece.
But Sampaoli showed he meant business for the second half as he took off his thick overcoat.
He also made a double substitution immediately as Gabriel Mercado, who lost Morgan at the back post for the opener, was hauled off to be replaced.
The Sevilla coach also threw on Stevan Jovetic upfront in a bold move.
But Sampaoli perhaps knew the game was slipping out of his reach when Sergio Escudero’s brilliant long-range effort hit the underside of the bar and bounced out.
Leicester duly went down the other end immediately and Marc Albrighton struck to make it 2-0.
The game was getting away from him and when Nasri saw red, so did Sampaoli moments later, receiving his marching orders and being sent to the stands.
Sampaoli is likely to be back in the Champions League next season – but probably not with Sevilla.
