It is tough to see how Zverev is going to have any impact in rallies when he playing nine feet behind the baseline.

Hello, Federer ace! We've missed you these last 48 hours.

After a couple of errors at the net, Mischa Zverev comes in and lands a clean volley for 30-30.

Federer sends his opponent the wrong way on a rally for 40-30 and holds when Zverev forehands wide.

Federer gets his own back and moves to 0-15, and then 0-30 when Zverev mucks up at the net.

The world number 30 does eventually get off the mark, and brings up 40-30.

He lands an nonreturnable body serve to hold.

Mischa Zverev nabs the first point from Roger Federer's serve but that's all the German is getting.

A standard hold for the seven-time champion.

Right then. One more match on Centre this evening.

Everyone ready? Got snacks? Got drinks?

We've cracked open the mini eggs. A treat all year round.

Djokovic on questioning the umpire’s decision: “Maybe it wasn't right saying me doing that and I apologise. It was frustrating because I thought the call should have been different. He is trying to do his job best he can, as am I. Sometimes it can just be said in the heat of the match."

Novak Djokovic speaking on BBC One: "I am delighted with my performance today, I thought I raised the level of tennis, comparing to the first couple of matches. This was the most focused I have been on the court and it came at the right time. Gulbis presents a great challenge; he is very unpredictable and has a huge serve. It's not easy playing on grass against someone like that.

"In general, I am pleased with the way I have felt and the way I played, I’m glad the crowd enjoyed it."

Centre Court's favourite son (ok, one of them) is up next.

Roger Federer returns to the grass as he bids to make the last 16 for the 15th time in his career.

The Swiss third seed is up against Mischa Zverev, who has never been past the third round before.

Mischa's younger sibling, Alexander, is already through. They are bidding to become only the third pair of brothers to reach the round of 16 at the same Grand Slam event in the Open Era.

Andrew Priestley: Andre Agassi is the happiest man on Centre Court with that straight sets victory. He was turning more and more red by the minute!

For the first time in a while I have seen Novak's passion back.

Novak Djokovic will face Adrian Mannarino of France in the next round - the two met last season in the second round. Nole won in straight sets.

Novak Djokovic is bidding to win his fourth Wimbledon title and move into joint-sixth place on the list for most Wimbledon titles won in history.

He defeated Rafael Nadal to win his first Wimbledon title in 2011, and won back-to-back titles in 2014-15, defeating Federer in the final on both occasions. He also reached the final here in 2013. Where he lost to?

Andy Murray of course!

Plenty of autographs for Novak Djokovic to sign, he's mastered the one-hand large marker pen signature of course. No signing of a camera though - has that fad died a death?

Andrew Castle
BBC Sport tennis commentator

That was a very accomplished performance. Djokovic really looks like he fancies this tournament.

Djokovic does his operatic salute thing to the crowd, who enjoy that very much.

Federer still to come...

Djokovic is pumped up, roaring again as Gulbis fires wide, and then moves to match point with another long return.
