Leeds United owner Andrea Radrizzani

Norwich City regret not selling Todd Cantwell to Leeds United during the last transfer window, Football Insider has been told.

The Premier League club submitted a £15million bid for the attacking midfielder in September and were in contact over a potential deal until the domestic window shut last month.

But Norwich refused to buckle and blocked the exit of their academy product as they remained firm on the asking price.

A recruitment source has told Football Insider that Leeds were put off by Norwich’s asking price of £20m for Cantwell.

However, the 22-year-old’s wretched start to the season has led to growing frustration among senior figures at the club and it is said there is “regret” over their stance.

There is a school of thought among the Canaries hiearchy they should have cashed in on the youngster, especially as he was so keen to leave.

He was axed for two league matches before the October international break and manager Daniel Farke also went public to criticise the player’s productivity and attitude.

Farke has subsequently been more positive about Cantwell and claimed on 20 October “he looked on a completely different level to when I compare him four weeks ago”.

Yet, this has not resulted in matchwinning performances on the pitch for a player who scored seven times in 40 matches last season when Norwich were in the Premier League.

Cantwell has yet to score in 403 minutes of senior action this season, which have been spread across five Championship matches.

Injuries have had an effect – he has missed the last two games with a hip injury – but he had been benched for the win at Bristol City prior to that after being hauled off at half-time in the 1-1 draw against Brentford on 27 October.

It remains to be seen whether Leeds will return for Cantwell, especially as they signed right-sided attacker Raphinha in a deal rising to £21m on the final day of the international window.

The Norwich man will enter the final 18 months of his contract at Carrow Road in January.
