The on-loan Bayern Munich midfielder made his debut against Newcastle United on Sunday, but his display was heavily criticised.
Since winning the European Championships with Portugal in 2016, Sanches has failed to kick on and he barely featured during Bayern’s title-winning campaign last season.
He had a mixed afternoon at the Liberty Stadium with some sections of the press complaining at his display.
However, Clucas insists he was not the only player to play below par and he is adamant he will bounce back.
Clucas told Wales Online: “It is unfair to only focus on Renato, there are 11 players on the pitch for us at any one time and I don’t think any of us did a good enough shift to win the game.
“Personally at the end I delivered two really bad set-pieces when we really needed them so it is not down to Renato, we have to look at ourselves collectively.
“It’s the same for anyone, if you don’t know the players and are from a different country and are learning the language it is going to be tough.
“Give the lad a week or two and he will be fine, we’ve already seen the quality he has in training. The gaffer has seen it and put him straight in.
“He is not at Bayern Munich for nothing, you don’t play for them if you are a low quality player. He is a talent, he might be looking to build his confidence and he can do that here.”
