Julian Alvarez’s potential move to Arsenal could be the biggest deal to watch, with the Atletico Madrid striker’s future now hanging in the balance.

The 26-year-old is caught between his desire to leave Atletico and the club’s refusal to sell him to Barcelona. But they would do a deal with Arsenal.

The Gunners have had a long-term interest in Alvarez and have been monitoring the dramatic situation, with Atleti looking for a fee of 150m euros (£128m).

Alvarez has missed multiple training sessions and did not travel to face Sevilla on Saturday, with Simeone saying he wasn’t well enough.

Simeone, meanwhile, has attempted to keep the door open, saying he will “do everything” he can to make Alvarez feel important when he returns to training.

After British and Commonwealth bantamweight title defeats, Maguire would avenge a previous loss against David Needham in 1975 to get his hands on the Lonsdale Belt – and in the build-up, reunited with Ali at Wembley.

In August 1977, they met again in the Grosvenor House Hotel for a testimonial in honour of Ali’s friend Paddy Monaghan, the Fermanagh-born bare-knuckle boxer.

By then, Maguire had drawn with European champion Daniel Trioulaire, while a second crack at the title brought a loss to Franco Zurlo before defeat by Johnny Owen proved his final stand.

“There were ups and down,” Maguire says of his career, “but it’s one I’m proud of.”

While his days in the ring were over, he would remain connected to the sport, serving as a member of the British Boxing Board of Control’s Northern Ireland Council.

On Saturday, Maguire will watch from home as Taylor, a trailblazer for women’s boxing, makes the same walk as Ali.

“I’ve had the opportunity to tell my kids and grandchildren about my time there, so for those boxing this time, they can do the same one day,” he said.

“Katie Taylor has had a great career and deserves her big night, but hopefully it’s not another 50 years before boxing’s back in Croke Park.”
