Bayern Munich striker Robert Lewandowski has refused to comment on speculation surrounding his future.
The 27-year-old, who has scored 23 times in 25 games for Bayern this season, has been strongly linked with moves to Real Madrid, Manchester United and Paris Saint-Germain over the past week.
The Polish international has admitted that constant speculation 'is not easy', but gave no indication as to his plans for next summer.
"Every year this speculation arises and I don't always react. I only care about football. It's not an easy situation for me, so I prefer not to say anything," the Pole told AS.
It was claimed last week that Man United were prepared to offer the forward close to £11m a year in wages in order to convince him to move to Old Trafford.
