Jürgen Klinsmann believes that both Manchester City and Inter Milan are strong teams and expects them to make deep runs in the Champions League.

Manager Pep Guardiola has suggested that Kevin De Bruyne might be a doubt for Manchester City's visit to the Etihad Stadium on Sunday after the midfielder was forced off with an injury during their match against Inter Milan.

De Bruyne was substituted at half-time during the game on Wednesday night.

The Belgian picked up an injury late in the first half after trying to race onto a through ball from a teammate.

Guardiola mentioned, 'The doctors told me he wasn't fit to play, but I was considering changing him at half-time anyway.

When you are alone and lose easy balls, it's a counterattack—it's impossible to stop it.

You have to be more precise.

It happened especially on the left side with Kevin.

We lost the ball without pressure, and when that happens, they can punish you.

'Despite starting their Champions League campaign with a draw, Guardiola insisted he was happy with City's performance.

'The displays will be better; with more time, we will be better.

We played so well.

I love my team; we are a fantastic team.

Inter are a team that defends really well.

They are masters of defending and transitions as well.

'Inter's best opportunity fell to a former midfielder, who blazed over the crossbar from inside the penalty area.

'I asked them to play exactly as they did.

We all know Manchester City and what they are capable of.

We knew we had to pull out all the stops and play a great game, and we did it.

When we work well as a team, we make it hard for everyone.
