Cristiano Ronaldo was the centre of attention in Switzerland on Monday, ahead of Manchester United's Champions League match with Young Boys.

The Portuguese striker scored two on his return to the Red Devils on Saturday, helping United beat Newcastle 4-1 at Old Trafford in the Premier League.

But he is back in European action this week as Ole Gunnar Solskjaer's side face the Swiss club in their first match of Group F, that also features Serie A side Atalanta and Villarreal, the Spanish side who beat United in last seasons's Europa League final.

All eyes were on Ronaldo again in Berne, though, as the former Real Madrid and Juventus star trained alongside fellow summer signings Raphael Varane and Jadon Sancho and the rest of his new United teammates before Tuesday's match.
