Ronaldo has struggled at Manchester United so far this season.

The Portugal captain has scored just three goals in all competitions so far this season for the Red Devils.

Ronaldo was unable to score in Man United’s last Premier League defeat to Aston Villa at Villa Park last weekend.

However, Ferdinand, a former teammate of Ronaldo at Man United, believes the 37-year-old might come back to Old Trafford in a better condition after the World Cup.

“Time will tell this season when you look at the end of the season in terms of goals and what he’s given back to the team,” Ferdinand said on Vibe with Five.

“Listen, there’s peaks and troughs in the season, there’s ups and downs in terms of form. Cristiano Ronaldo, right now, isn’t hitting the net like you’re accustomed to seeing with Cristiano.”
