Pochettino 'upset' by late goal despite Chelsea rout as Blues reach Wembley

Mauricio Pochettino was upset that his side's dominant victory could not come with a clean sheet after Chelsea defeated Middlesbrough 6-1 to secure a place in the Carabao Cup final.

The Blues arrived at Stamford Bridge with a one-goal deficit to overcome after Middlesbrough's first leg victory at the Riverside two weeks ago. Pochettino's side never looked like scoring on that occasion and put in a contrasting display on home turf.

Chelsea produced a clinical opening half, first forcing Jonny Howson into an own goal after a smart forward move, before Enzo Fernandez, Axel Disasi and Cole Palmer each put Middlesbrough to the sword. Noni Madueke joined the group on the scoresheet in the second period before Palmer added his second as Conor Gallagher found two assists.

The west London side were able to coast to an extent but that provided a moment that Pochettino was less than happy with. Morgan Rogers was able to cut onto his right foot and direct a shot from the edge of the box past Djordje Petrovic in the 88th minute.

Chelsea's head coach wants to see his side 'play seriously' for a complete game. It was an incident that put a small dent in his pleasure from the victory.

"I was really upset because we need to learn from that," said Pochettino following the game. "We need to play seriously until the end. Sometimes it looks like you didn't finish the game and you lost a bit of focus.

"We are disappointed to concede the goal but we need to use every single second to improve. It didn't kill my happiness but I was a little bit disappointed with the finish to the game."

Pochettino believes that the match and progress to Wembley will provide a positive impact on the growth of his young team however. The 51-year-old was pleased to see
