Chelsea made it to the quarter-finals of the FA Cup with a 2-0 victory over Wolves.

Despite the home side's lowly position in the Championship, Paul Lambert's side had a go, and in the first half George Saville lashed an early strike against the post.

Eventually, class told and Pedro stole in to head home unmarked at the back post.

Diego Costa sealed Chelsea's place with his 16th of the season as he slid a low finish past Wolves keeper Carl Ikeme.

Here's what we learned from an entertaining FA Cup tie.

First leg: Andreas Weimann of Wolves (R) fouls Willian

Deputising for N'Golo Kante is the hardest job in football

Antonio Conte decided to give a number of key men the day off, and one of them was the player of the Premier League season so far.

It was always going to be a huge ask for young Nathaniel Chalobah to emulate Kante – and he never really tried to here.

A competent role in the game would have been enough at this stage in his development.

But this team is so used to working with Kante at its core, that play entirely passed Chalobah by.

Kante was given his chance off the bench towards the end, and he played a role on Chelsea's second.

He is always missed.

Heads up: Nathan Ake (C) is first to the ball

Meanwhile, Fabregas did rise to the occasion

Chelsea were dour and uninspiring and a number of senior players looked like they didn't fancy the challenge.

Cesc Fabregas was not one of them.

It is easy to say that highly paid and experienced players should automatically perform against lower league sides, but Molineux is not an easy place to go.

Fabregas worked hard, and put in his characteristically impressive passes: everything Chelsea did well, somehow involved him.

Though one man cannot carry a team.

Armed: Diego Costa of Chelsea (L) and Danny Batth get involved

But the performance was never important here

Conte made changes, and the aim was to do enough to win.

Few will be rushing out to buy a DVD of this game, and if there are any lessons to be learned it is in the way untried players do and don't fit together.

But Blues did enough to go through: and that is all that truly mattered here.

Warrior: John Terry at Wolves makes himself heard

Pedro stepped closer to emulating an all-time great from the past

With his goal here, a well taken move he started and finished, Pedro followed in some auspicious footsteps.

While his all round performance, albeit out of position at left wingback, was not vintage – this game continued the trend of him scoring in every round of the cup so far.

That was famously done by Peter Osgood – who scored in every round on the way to Chelsea's first FA Cup triumph in 1970.

There's a way to go yet, not least the small matter of a sixth round draw: but that is a mighty aspiration fro him to keep up.

The FA Cup isn't quite dead yet

First there was Lincoln's magical win at Turf Moor – non-league knocking out Premier League.

Then Millwall ended champions Leicester's chances of any domestic silverware.

This game never rose to that level of drama or romance, but there was one remarkable thing to note at Molineux.

The attendance of 30,193 was Wolves' biggest at home since 1981 – and a record for the rebuilt stadium.

We know there's great passion for the FA Cup in west London: but they're barmy about it in the Black Country too.
