Mauricio Pochettino left Enzo Fernandez gobsmacked after the Chelsea boss hilariously nutmegged his own player in training. The Blues were put through their paces on Friday at Cobham training ground as they prepare for a blockbuster clash with Arsenal.

Chelsea will welcome the Gunners to Stamford Bridge on Saturday afternoon as either side hopes to extend their respective streaks. The west Londoners secured their third successive victory across all competitions just before the international break with an eye-catching win over Burnley.

More impressively, Arsenal stormed past Manchester City at the Emirates Stadium earlier this month to keep their unbeaten start to the Premier League in tact. Now, Pochettino and Mikel Arteta will lock horns in what is expected to be a fiery tie.

While it's a huge game, the Chelsea boss still has time to crack a laugh on the training pitches at Cobham. In the Blues' latest training video posted on YouTube, Pochettino hilariously nutmegged Deivid Washington leaving Fernandez scratching his head.

The 18-year-old striker, who the west Londoners signed from Santos late into the summer transfer window, was in the middle of the rondo and, after a cheeky step-over from his manager, he was quickly nutmegged. Later in the training video, the likes of Armando Broja and Raheem Sterling were spotted completing shooting drills and gym-work.

Speaking in his press conference on Friday afternoon, Pochettino previewed the Arsenal tie. He said: "I think we are confident, the team is confident, the players have different mood than one month ago and I think too many positives.

"Still fighting, still struggling with some injuries of players we cannot recover 100% but working really hard to find solutions and of course, very positive."

Then, on what it would mean to get a good result, Pochettino added: "I think we are thinking we need to win tomorrow, with respect to Arsenal, they are a great team. You know very well, that Mikel is part of my family, we are going to meet him tomorrow.

"It is going to be tough because they are doing a great job. Very good squad, very good team. They are playing so well they are competing for everything to win, not only the Premier League, the Champions League.

"They are doing fantastic, it's going to be tough but also we are confident we can give our best and give a very good game."
