Alonso's side had to work hard during our first competitive home outing of the season. The Hatters sat deep and in a compact shape; it was not an easy evening.

That was reflected in the fact that the game was goalless at half-time. However, five minutes into the second period, we broke the deadlock as a wonderful cross from Malo Gusto was headed home by Danny Welbeck on his Chelsea debut.

Victory was secured as the game moved toward its conclusion. Estevao Willian played a key role in the goal, driving a shot toward the far corner that defender Hakeem Odoffin could only turn into his own net.

Our win – and the manner of it - was vindication for the strength of the starting XI named by Alonso. He was not taking the Hatters lightly.

'We always want to choose a competitive team, he said. 'We are taking all the games seriously, and we are in a moment in the season where many things and processes are starting.

'I’m happy many players had their first minutes for the club, making their debut and playing their first competitive game in this stadium. It wasn’t easy - credit to Luton, as they made it difficult – but we played with conviction and patience, knowing the first goal was going to come in a moment, and Danny took it really well.'

The post-match stats highlighted our dominance across the 90 minutes. We enjoyed 65 per cent possession, registered 26 shots, 45 touches in the opposition area and limited Luton to just one shot on target.

It's why Alonso again described his side's display as 'serious' and emphasised how the game could prove beneficial for the Blues during the season ahead.

'For sure, it’s a performance to learn how to attack a low block. Against a 5-4-1, it’s not easy against any team from any league. We need to learn from today, as we will face this context in other games as well.'
