if Cristiano Ronaldo wants to win the Champions League again this season then he should have stayed at Manchester United .
The former Barcelona striker cannot see Real Madrid's new look collection of multi-million euro signings gelling well enough to conqueor Europe.
After watching them play their opening game, Lineker thinks that Ronaldo has made a mistake if he has the ambition to retain the trophy he helped United win in Moscow in 2008.
"I had no problem with Cristiano Ronaldo joining Real Madrid this summer. Players want to move clubs for lots of different reasons. Sometimes they just fancy a fresh challenge," he wrote in his Mail on 'Sunday Column'.
"I understand that, I did it myself. But for this season at least, I think Ronaldo would have had a better chance of winning the Champions League if he had stayed at Old Trafford.
"[Madrid president] Florentino Perez tried it before, of course, but it did not work then, with Zidane, Beckham, Figo and the Brazilian Ronaldo because the balance of the team was not right. Great going forward - but always likely to concede goals.
I can see the same problem for Real this season. I watched their first La Liga game, against Deportivo.
