Ander Herrera has named Zlatan Ibrahimovic a “genius” but revealed the Manchester United striker’s competitiveness is “annoying” at times.

Ibrahimovic’s capacity to transfer his prolific goalscoring form from France – where he scored 44 goals in his last season at Paris Saint-Germain – to English football was questioned ahead of last summer’s switch to Old Trafford.

However, a sensational debut season for United – which has yielded 26 goals, two of which sealing Community Shield and EFL Cup glory – has silenced his doubters.

“He is a genius,” United team-mate Herrera told Marca. “He can say that he will score 30 goals and that he is the best because he can get away with it.”

“He is so good that he can do that.”

Ibrahimovic’s goalscoring exploits have been matched just by his unwavering confidence in his own capacity, with the Swede claiming to have foreseen the success he has brought to United.

The unrivalled willingness to satisfy his own prophecy and prove his doubters wrong continues to play a vital role for Jose Mourinho’s men, in spite of the fact that, as Herrera includes, this drive can become disappointing.

“Ibrahimovic can be very annoying,” the Spaniard said. “He can be very annoying because he wants to win it all, even at football-tennis.”
