Calum, signed on an initial three month loan, would like to stat until the end of the campaign and he says:
"I haven't heard otherwise so I imagine Tottenham will let me stay; I am happy here and playing regular football and if we win our next couple of games we will be sitting in a nice position and things will be looking good.
"Hopefully something can be sorted out and we can take it from there; it will be good for me because at least then I know what I am doing for the rest of the season, which will be nice.
"The main thing is if I went back to Tottenham I would probably be a little bit frustrated, because I imagine I would be travelling and not really featuring.
"As things are at the minute I am happy and that is all that matters - hopefully West Ham are happy as well.
"Obviously I look out for Tottenham's results but my main aim at the minute is performing well for me and West Ham; I am focusing more on them than Tottenham at the moment."
He is confident that the Hammers can close the gap on unbeaten Wigan sooner or later and adds:
"They seem to be firing but I am sure at some stage they will hit a sticky patch and maybe we can catch up a little bit; they will lose a few games at some point."
Calum is still looking for that elusive first goal in claret and blue and adds:
"I got on the end of a couple of corners on Saturday but I lost them in the sun; I am getting closer and it would be nice to see one drop in.
"But I don't know what I will do if I do score - I think it will just be a sigh of relief!"
Plymouth was Calum's comeback game after a short spell on the treatment table and he adds:
"I have had to sit and watch which is not nice but I am back fit now and playing, which is the main thing.
"I just had to give it a couple of weeks to make sure it settled down properly, which it has done, and hopefully that is behind me now I have 90 minutes under my belt.
"We didn't create as many chances as we should have to win but we have all watched the game again and with the ref it was quite stop-start all the way through - he was blowing up for this and that, and he didn't have one of his best games."
Calum replaced Anton Ferdinand, who was at the heart of the defence at Chelsea last week, and he says:
"They did well, we could have taken them to extra time, but it wasn't to be - though the lads were proud of their performance."
He is expecting a cracking game in Wales on Tuesday night and adds:
"The Cardiff fans are passionate, as are the West Ham fans, and I am sure it will be a great atmosphere down there - these are the games you want to play in and let's hope we come away with the right result.
"I had never been down to Plymouth but credit to their fans, it was a good atmosphere with their 20,000 of them and our end sold out - and it will be the same at Cardiff."
