Former Man Utd player Luke Chadwick believes rivals Man City are ‘suffering’ without a goalscorer such as Cristiano Ronaldo.
The Portugal forward returned to Old Trafford on transfer deadline day in a deal which could rise to £19.8million.
Before Man Utd swooped in, Pep Guardiola’s Man City were interested in a deal.
The reigning Premier League champions were looking for a new striker to replace Sergio Aguero, who joined Barcelona in the summer.
They also submitted a £100m bid for England captain Harry Kane but saw it knocked back.
City have picked up three wins from their opening five Premier League matches. They have also beaten Bundesliga outfit RB Leipzig in their Champions League opener.
However, they were left frustrated on Saturday as Ralph Hasenhuttl’s Southampton held them to a 0-0 draw.
When asked about City, Chadwick told CaughtOffside: “It’s dangerous to write City off. They had a poor start by their standards last season but went on to win the league at a canter. They’ve had some good performances and some indifferent ones.
“The main story is the Harry Kane one – they missed out on the striker they were looking for, and Aguero’s gone off to Barcelona, so there’s not really a 25-30 goal-a-season player in their squad. They’ve had some negative press as well in terms of struggling to fill their ground. It was a poor result against Southampton.
“It’s good from United’s point of view to see City struggling, but I don’t think you can really write them off. What Guardiola’s done in the past, the talent he’s got in his squad, you’d expect him to find a way for the team to be there or thereabouts come the end of the season.
“If you put Ronaldo in the Man City team they’d have won a few more games this season. He’s so intelligent with his movement and the start he’s made at United is staggering, especially at his age. Four goals from three games – you’re not really surprised by it, every time he plays you expect him to score.
“City missed out on Harry Kane, they seemed close to Ronaldo as well, and now they’re suffering for it. The talent United have up front is probably the best in the Premier League this season.”
