The City director of football feels Real Madrid can be unstoppable.
City, who knocked out Paris Saint-Germain in the quarter-finals this week, will be hopeful of getting the better of Real – who struggled to beat German side Wolfsburg in the final eight.
Now there has been an instant reaction from Manchester City regarding the tie.
"Real Madrid have shown that in the return leg at the Bernabéu, they are unstoppable"
Madrid trailed Wolfsburg 2-0 in their quarter-final tie but won 3-0 at the Bernabeu to turn it on its head and make the final four.
Begiristain, who will know plenty about Real considering his experience of Spanish football, is right to be wary.
On their day Real are fantastic but Manchester City will probably rather face them then the other semi-finalists Bayern Munich or Atletico Madrid.
Manchester City will be hoping to halt the march of Europe’s most decorated club as Pellegrini looks to end his career in England on a high.
