Malcom had been on the verge of joining Roma in July, with the Serie A club and his former side Bordeaux announcing an agreement had been reached.
But Barca came in at the 11th hour and secured a €41million deal for the talented winger, leaving Monchi incensed.
And in N’Zonzi – a €26.65million addition from Monchi’s former club Sevilla and member of France’s World Cup-winning squad – he thinks he has succeeded.
“We have been impressed with Coric and Zaniolo. Very impressed. But clearly we have a lot of midfielders right now. A Serie A loan might be best for them.
“Doesn’t a world champion seem stronger than Malcom to you? For me Steven is better than Malcom.
“We already have stronger players on our team. We have improved the team without thinking about the defined roles.
“Malcom was a possibility because he seemed strong, but we went ahead looking for both the same and the other players.
“Ten days ago, it was impossible to sign Steven due to an economic reason, but thanks to the desire of his agent – who is his dad – to come here and the effort of the club, we succeeded. Nothing has changed. We have taken a strong player.”
N’Zonzi had a difficult start at Sevilla after Monchi brought him to LaLiga, but he went on to establish himself as one of the best midfielders in Spain and leaves the Ramon Sanchez Pizjuan as a World Cup winner.
But it was not success in Russia that prompted his desire to leave, with the Frenchman – who attempted to force a move in January after falling out with Sevilla’s management – wanting a new challenge.
“No, it was not that [winning the World Cup],” N’Zonzi said. “I spent three wonderful years in Seville, but I felt the need for a new challenge and I chose a great club that will help me grow.
