David de Gea's job as Manchester United's goalkeeper got significantly harder over the summer, at least as far as training is concerned.
As one of the world's finest shot-stoppers, most strikers in the world would stutter if they found themselves in a one-on-one situation with the Spain international, but Zlatan Ibrahimovic is not most strikers.
The 34-year-old Swede arrived at Old Trafford on a one-year deal after an incredible final season for Paris Saint-Germain in which he scored 40 goals across all competitions. While it would be unfair to expect him to repeat that feat in the Premier League, the pressure to perform is sky high.

His debut only justified fans' excitement. Ibrahimovic managed to score an acrobatic scissor-kick just four minutes into the game against Galatasaray which the Red Devils went on to win 5-2.
Considering he only linked up with his new team-mates last week, he certainly looked comfortable in his new surroundings and De Gea has since confirmed that Ibrahimovic is already feeling right at home.

"It's really good to have Zlatan already here, training with the team," the Spaniard said, according to the Daily Mail.
"You can see he's a top player, he's massive, very big, with a lot of quality and of course he is a top striker. I think he will settle in very quickly. You can look and it seems like he has been playing here many years already."
De Gea was equally complimentary about Jose Mourinho's other signings so far this summer, Eric Bailly and Henrikh Mkhitaryan.
"It is same with the other guys we've signed," De Gea said. "They are playing really well, their training has been top and I think that we have signed really good players."
It is clear the exciting surrounding Ibrahimovic's arrival has transcended the stands and made its way into the dressing room. De Gea is clearly happy to have the mercurial star on board while youngster Marcus Rashford recently said he is hoping to soak up as much advice as he can.
"We can definitely all learn from him while he is here, so we all need to take that chance," the teenager said.
"It's a massive help to be with him every day and it's great to see what he is like on and off the pitch. There is a lot to learn from him and hopefully I can bring some of his game into mine."
