Luke Steele has welcomed the signing of fellow goalkeeper Ben Alnwick but would like Barnsley manager Keith Hill to specify who is the first choice.
Hill says he wants 'two number ones' battling for the starting position but Steele – who was player of the year last season – thinks it works better if everyone knows who is first choice.
"Goalkeepers are not like other positions in football when players can come on as subs and do well and then maybe get in the team in the next game," said Steele.
"I think it works better when you have someone who is number one and someone who is number two. If you are constantly changing the goalkeepers around then no one gets enough match practice to be at their best.
“I remember when Heinz Muller was here, he didn’t like it when I was brought in as another first choice goalkeeper because he wanted to know he was first choice."
Alnwick, 25, joined the Reds on a two-year deal last week after being released by Tottenham Hotspur.
Steele said: “I hadn't seen much of Ben before he came to Barnsley but he looks like a good, solid 'keeper and I am looking forward to working more with him.
"I know we need to have a more experienced goalkeeper as we have Lukas (Lidakevicius) who is only 19 then very, very young ‘keepers after that. If I am not playing well then I know I could be replaced.”
