Manchester United vs Barcelona promises to be a blockbuster International Champions Cup clash in Santa Clara on Saturday.

United have won both their matches on the preseason tour of the US so far, even if neither of them have been too convincing.

The first one was a 1-0 victory over Club America, thanks to an early goal from Morgan Schneiderlin, while the second was a little more straightforward.

Memphis Depay took the spotlight from that 3-1 victory over the San Jose Earthquakes, but Louis Van Gaal, who played two different teams in both halves of both games, will know a lot of improvement is necessary with the Premier League season just two weeks away.

Van Gaal said this time around against Barcelona, there won't be two different XIs in two halves, with his preferred team likely to play 60 minutes.

"We have to improve our shape and, of course, our level and we have different organisations, so we have to play with different organisations," van Gaal told MUTV. "Also, we have to improve every level that we have, in all the positions.

"And, of course, I have to select now already for the third match against Barcelona.

"Now 11 players can play 60 minutes and that's a big difference, so the next match I will show already what I find from the first two matches because the players have to prove their level on the pitch."

All four new signings of Manchester United – Matteo Darmian, Bastian Schweinsteiger, Memphis Depay and Schneiderlin – have got some much-needed game time in this International Champions Cup tournament, and it will be interesting to see which of them makes the Van Gaal-play-for-60-minutes cut.

While this will be Manchester United's third match on tour, Barcelona have only played one game so far – a 2-1 win over the LA Galaxy. Luis Suarez was on the scoresheet for Barcelona in that game, and with Lionel Messi and Neymar missing from this tour, expect the former Liverpool man to take centrestage again.

Barcelona also face Chelsea on their tour of North America, and Luis Enrique will know playing such difficult opponents from the Premier League will put his squad in good stead ahead of the defence of the three titles they won last season.

Van Gaal only has two more matches, including this one against Barcelona, to get his players ready before the start of the Premier League campaign, and a win against arguably the best club team in the world at the moment will be a huge confidence-booster for Manchester United.
