United are a couple of days into a week-long stay at our Andalusia base, with friendlies against Cadiz and Real Betis on the horizon. Those games will be played on Wednesday and Saturday respectively.
"[It's] not [just] to keep fit, [it's] to get fitter and to improve in the fitness levels. If we see the season so far, especially in the front line, we didn't always have the players available," said Ten Hag.
“When they were available, they were not always capable of being at the right fitness levels to compete.
“This is an important objective: to fill that gap, to close that gap and that we are better after the winter, in the restart. To be better and to compete and to match the fitness levels in the Premier League and in the top four."
He also told mautd.com: “I think they are two good opponents playing in La Liga, which we all know is a good competition, so we know it'll be a challenge in both games.
“Cadiz played against Real Madrid in their last game and only lost 2-1, so we know it's a tough opponent. And Betis also, we know, it's a really good opponent, so we are really looking forward to working on our way of play.
“As I said, it's a good challenge and a fantastic opportunity to show themselves."
