The former captain says he isn't surprised by his old side's current position in the Premier League.
His former club are currently fourth in the table, one point behind Arsenal who are third but a massive ten points behind Chelsea who are currently leading the Premier League.
United are only one point behind fifth placed Liverpool though, with them, Tottenham and Southampton all also competing for those final Champions League places with Van Gaal’s side.
Despite the relatively good position in the league though, there has been murmurs of dissent that United are not challenging for the title under the Dutchman, with their style of play coming in for criticism.
Keane though, says he isn’t surprised by their current position at all, blaming the recent raft of changes at the club as a cause.
"I've not been surprised by where United are currently under Louis van Gaal,” said Keane.
“There's been so many changes over the years at the club, it's expected. Lots of experienced players leaving and people shouldn't be surprised at where they're at.”
As previously mentioned, there have been murmurs of dissent and criticism from all angles about United’s style this season, with former players and opposition managers all giving their opinion on the matter.
Keane however, says there’s been progress at his old club during the last few months, although he does admit that the fans would prefer their side to play better in the final third of the pitch.
"There's been progress over the last few months,” added Keane.
“What's helping is they're getting decent results, performances haven't been great, and the fans would like some quicker play in the final third."
