He failed to limit himself in Manchester United's 2-0 victory over Arsenal last week.Martinez, 25, joined the Red Devils from Ajax for around £57 million last summer. He helped them finish third in the Premier League standings and lift the EFL Cup past campaign, featuring in 45 matches.Real Madrid ace Jude Bellingham opens up on what Manchester United player told himAfter Real Madrid's latest friendly win against Manchester United, Jude Bellingham claimed that he and Lisandro Martinez showed respect for each other at the end of the contest.Bellingham told reporters (h/t GOAL):"The tiff with Martinez is one of those things. He is a brilliant player. I came in at half-time and I was f'ing this and f'ing that. But when he came over to wish me all the best when he came off, I respected it. I know that what happens on the pitch, always stays on the pitch."Bellingham lauded the former Ajax centre-back's fighting spirit, adding:"I saw him at the end of the game and wished him well. I do respect that when two players are trying to win for their team and can come together and be respectful after the game. He is a great competitor and a great player. Just like me, he wants to win. At times, it spills over. That is part of it. We can have that moment after the game."Bellingham, 20, is next set to be in action in Real Madrid's two remaining friendlies against Barcelona and Juventus on July 29 and August 2 respectively. He will likely make his competitive debut for his club in their 2023-24 La Liga opener at Athletic Bilbao on August 12.Martinez, on the other hand, is expected to play in Manchester United's final three friendlies against Borussia Dortmund, Lens, and Athletic Bilbao on July 30, August 5, and August 6 respectively.
