Mooy has been a regular under Potter this season, since joining the club initially on loan from Huddersfield, while midfielder Mac Allister is due to link up with the squad after next week’s home match against Watford having completed international duty with Argentina in the Olympic Games qualifying tournament.
Perhaps the most intriguing addition is 19-year-old Lamptey, who made his Premier League debut for Chelsea last month. Known as a right-back, he can also play in midfield.
Potter said, “He’s a young guy who’s had a nice foundation at Chelsea who is looking to progress his career and help us.
“He’s not the solution in the immediate sense and we’ve got good options in that position, but he will help us long term and he will provide a freshness in the group in training.
“I know his attributes. He’s very fast, with and without the ball, and in the final third he can affect the game because he can play further up the pitch.
“Everyone knows my thoughts on the transfer window – for me February is a great month!

“But I’m happy with the players we’ve got and I think there is enough in the group we already have to get the points which will get us higher up the table, but I also know we can improve.”
Potter believes Saturday’s 3-3 draw against West Ham, when Albion came from 3-1 down to earn a deserved point, showed the desire in the squad which will be needed in the remaining months of the season.
“There are moments in the season when you need to fight and show character and I thought we had that in abundance,” he said. “It’s the Premier League, it’s supposedly the hardest competition in the world and in nearly 120 years we’ve been in the top-flight for seven years. We are where we are and sometimes we won’t be successful - but we will fight.
“Hopefully the supporters who were there went home quite happy and proud of the team. I think they enjoyed what we tried to do and the character we showed."
“I also thought both subs had an impact. [Ezequiel] Schelotto’s drive and personality pushed them back. Solly [March] has had a frustrating time with injury, but he keeps pushing and pushing, and I am glad he was able to contribute as well.”
