Manchester United striker Radamel Falcao has claimed his critics will be silenced when he returns to action and starts scoring goals regularly.

The Colombian international garnered a reputation as one of the most clinical strikers around Europe during his spells at Porto and Atletico Madrid.

However, a number of injury concerns since his sensational deadline day move to Old Trafford have prevented him from making the impact expected in the Premier League.

Falcao has only managed to make five appearances for Manchester United, and having only scored one goal, some have questioned whether he will be able to replicate his best form at his new club.

Asked during an interview with DirecTV Sports how is he coping with the scrutiny and how he will turn around the situation, he said: "Probably as soon as I play and score goals they will stop talking.

"I have to try and ensure that everything that does not add something positive to me doesn't damage me. There is a lot of speculation but I have to try to isolate myself from it.

"When a player comes to a new league, with the numbers like I had in my previous clubs, it is normal there are high expectations. Unfortunately I have had to sit out a few games due to the injury.

"I've played five games, three of which I started. What I needed was to play to get used to the new league and when I have played I believe I have not had any problems. I think I've played well. I am very calm and happy."

The Colombian international has been unable to play since suffering a calf injury in training ahead of the Chelsea clash on 26 October but after returning to training on Monday he is expected to be ready for action soon.

Asked about Louis van Gaal's methods and philosophy, Falcao said: "He is very studious in terms of the tactics, and he likes nice football but at the same time with a direct style."
