Messi, who spent four seasons alongside Neymar at the Nou Camp, admits he would not like to see the 26-year-old at the Bernabeu.
Barcelona striker Lionel Messi is nearly certain to win this year's Golden Shoe* award for the leading goalscorer in league matches from the top division of every European national league.
"And on a football level, it would make Madrid much stronger than they already are".
The 33-year-old forward missed Saturday's 6-0 La Liga victory over Celta Vigo - and the 3-2 win over Sevilla in the previous match - with an ankle injury sustained in the 2-2 draw at Barcelona earlier this month.
Messi, the five-time World Player of the Year, said he was looking forward to the tournament in Russian Federation and was targeting at least a semi-final place with Argentina. "They are great players and hopefully I become happy with these comparisons". The Sunday Mirror said Real Madrid have been "hovering" and Neymar's father is thought to have asked agent Pini Zahavi to organise his son's transfer to the Champions League finalists as soon as possible.
"I'm not tempted to leave Barca", Messi told TyCSports.
"I want to challenge myself and test myself against the best players in the world and there are not many people better than the likes of Ronaldo. I fight to win everything and I don't need to go anywhere else to prove anything", he claimed. It stimulates me to see Real Madrid again in the Champions League final, to see them winning leagues. The Ligue 1 player of the year said: "My goal now is the World Cup. It's what we all want".
