He has been starring regularly for the Dean Smith led side who revealed he is happy to have the player extended his contract.
“I have been really pleased with Sergi and he has been progressing really well. Even though he is only 18-years-old, he has quite an old head on young shoulders.
“He has impressed me so far. He wants to learn and he wants to get better. He is enjoying himself here and he gives us something that we haven’t really got here in terms of his direct running and enthusiasm. It is encouraging to have a player like Sergi here for the rest of the season.”
He joins some of Liverpool youngsters on loan and he is expected to form part of the future of the club.
There were wide reports recently that Jurgen Klopp usually monitors most of his youngsters on loan as he is keen on given them chances.
