Montezemolo admits he misses Schu ‘at times’
The seven time world champion is Ferrari's most successful ever driver, winning five world championships during his 1996-2006 tenure.
But after retiring four years ago, the 41-year-old returned to the grid this year with Mercedes, and the tension between the German and his former camp has been obvious.
"We had beautiful years together and I gave him back his desire to race," said Ferrari president Montezemolo, referring to the offer of a temporary seat last year to replace the injured Massa, which subsequently became a full return with a rival team.
"At times I miss Schumacher, he gave so much to Ferrari, but he also received a lot," the Italian told La Gazzetta dello Sport.
He then referred to the forthcoming Partita Del Cuore charity football match, to be played in Modena early next week and featuring current Ferrari drivers Fernando Alonso, Felipe Massa and Giancarlo Fisichella.
Said Montezemolo: "A few days ago I was tempted to call him (Schumacher) to ask him to play for us. But as the team carries the Ferrari name, I avoided it."
