Manchester United striker Robin van Persie is convinced they have plenty of room for improvement in the second-half of the season.
The former Arsenal captain argues the new signings are still getting used to eachother.
"I feel that we are getting better. We had a sloppy start to the season where everyone had to get used to each other, but that makes sense.
"We are now more and more automatic amongst the group and the majority is fit," said Van Persie.
