Being in a different league to the Premier League, he’ll have more opportunities, more chances to showcase his football and do something big there.“He’s a fantastic player, no doubt about it and I think he’ll make a real impact. Definitely a brilliant signing.”Rashford’s Old Trafford future was deemed practically over when the club handed his No10 shirt to new signing Matheus Cunha.And he had been looking for a new home after falling out with Ruben Amorim leading to him spending the second half of last term at Aston Villa and being forced to train away from the first-team at Carrington.Rivaldo said: “When a player leaves a club in a tough situation, like he did, and joins a team like Barcelona. “It’s only natural that the coach will use training sessions and the first few matches to get a better look at him.BEST ONLINE CASINOS – TOP SITES IN THE UK“Barcelona had a great season last year, so it’s normal for him to start off on the bench. “Little by little, he’ll find his rhythm, start to understand how the manager wants the team to play, get used to the training routines, and gradually settle in. Over time, he’ll earn his spot. “He’s a hugely talented player — he’s already proven that in one of the toughest leagues in the world. He’s also an international. So, I fully expect him to earn a place in Barca’s starting XI and re-establish himself as a regular in the England squad too.”
