Former player and tennis analyst Mark Petchey doesn't think Alcaraz can win 20 grand slams but he believes that the Spaniard will have a huge impact as Bjorn Borg did.
Petchey compared Alcaraz to Borg in the type of legacy they will have in tennis. Borg is a legendary player whose impact on the game is very noticeable and Petchey could be something like that for Alcarza. The Spaniard has a long way to go to get to Borg's level but Petchey believes he can do it. He doesn't think he'll ever catch the big three.
He wrote:
"I don't believe @carlosalcaraz is a 20 time Major Champion as this number has become become ‘normalised’. He may not win 10. However, just like Bjorn Borg, I do believe he will be one of the most influential tennis players the game has ever had with the way he plays."
