Robert needs to get some match practice. We expect him to play the two Under-21 games in full.

It is a competition just like over the rest of the pitch.

Physically he is not fully fit at the moment and he urgently needs to win match practice.

We know what Didi can do.

Didi will have to stay in England for the next few weeks as he has to find his rhythm at Liverpool first.

He'll stay in England to find some rhythm with Liverpool. Last season he was a late starter and went on to win the Champions League.

All four will play from the start.

I do not agree with this theory that a goalkeeper needs security. Both players have raised their level because they are being pushed.

Didi will be staying in England for the next few weeks so find his rhythm with Liverpool.
