Walsall defender Rhys Weston says increased competition for places at the Banks's Stadium is powering their challenge for the play-offs.The Saddlers are only a point off the top six and play rivals Millwall next. [LNB]Weston told BBC WM: "I think that's what the management have been striving towards since they came in. [LNB]"I think complacency as a footballer can be your worst enemy. The fact we have got competition in every place now is only going to benefit the team." [LNB]Weston has been weighing up the possibility of the unfancied Saddlers continuing their play-off push into the spring and whether it represents the best chance since he joined the club. [LNB]He said: "It's difficult to say. Time will tell. We're still a small squad and we're a young squad. We're getting better and better as we go along.[LNB] [LNB][LNB] "We had a bit of a wake-up call against Southampton - barring their points deduction they'd be in the play-off places now, which is a fair reflection of the resources they've got and the team they've got - but we're still up there. [LNB]"If the management will deem a few additions necessary in January I don't know, but all we can do, whoever is selected on game day, is go out and do our best and try to hang on to the shirt-tails of the teams above us." [LNB]The 29-year-old will reach the milestone of 100 appearances for the Saddlers if he turns out against Millwall on Saturday. [LNB]But goals have been thinner on the ground for a player who has scored just three in 331 games for Arsenal, Cardiff, Port Vale and Walsall. [LNB]"From a purely selfish perspective, scoring the goal against Stockport last year was good for me and I think I've averaged a goal about every 100 games since I came into professional football so when they come along I like to savour it," he said. [LNB]"There's been some good times, obviously beating Leeds last season was a big occasion. [LNB]"I came to Walsall to play games and get myself back on the map and I think the fact I've played nearly 100 games has proven that I'm back in the fold again."
