Ron Dennis says it's too early to judge McLaren's changes

With an overhaul of its design staff nearing completion - following the arrival this week - hopes are high that McLaren is putting in place what it needs to get back to winning ways.

Dennis, who has worked closely with racing director Eric Boullier to bring about changes at McLaren, says that the fact the team is altering things quietly behind the scenes may not deliver a headline-grabbing impression of a revolution.

However, he is clear that things have changed a lot - but accepts it may take time for the results to show.

"There will be more changes over the next three months, but primarily to basically make sure the machine works properly," said Dennis, when asked about his feelings on the new structure in place at the team.

"When you bring people together you bring their personalities together, and that doesn't come out for a month or two. Then you've got to shape everything to make sure it all works smoothly.

"When a new huge sponsor comes in, for example BAT, the first thing they do is build new motorhomes and build new trucks. They come like a big new circus and boom! But they find the results are a little bit more hard to come by.

"The inevitability is you want to look different but actually that's not where you've got to start. All of how we look and what we do will come later - it's a complete change and it will just take time.

"Race results of course, as ever, will be measured every two weeks, but really I want the company to be measured in a year or two when everything has fallen into place."
