Bradford City’s star striker Nahki Wells won’t be talking about this goalscoring exploits just yet following a gag imposed by the club.According to the Bradford Telegraph and Argus, the Bantams have enforced “a vow of silence” until 11.01pm next Monday, when the summer transfer window closes.Wells smashed a club record on Saturday when he netted both goals in the 2-0 victory over Sheffield United. He became the first City player to score in eight successive games — three at the end of the last season and in every game since the new campaign started.Saturday’s double made it nine goals in eight games.The previous record of seven was held by David Layne, who achieved the feat more than 50 years ago. Prior to that John McCole and Jack Deakin had also scored in seven successive games.A number of clubs from League One and the Championship have been monitoring the Bermudian’s progress and it’s expected that at least one of them will be making a bid.But, according to the club, the “not for sale” poster remains in place.Bradford’s assistant manager Steve Parkin insisted that the 23-year-old Bermudian, who fired in 26 goals last season, was not available.“People have had more than 12 months to come and sign him and they’ve not bothered,” said Parkin after Saturday’s match. “We’re not going to sell him the week before the deadline.“Both chairmen let us put a squad together to get promoted last season and hopefully we can get promoted this season. You don’t sell your best players if you want success. It is a no-go area.“It is terrific when you have a goalscorer like Nahki in the team, but he has a long way to go and it is important that he keeps his feet on the ground and keeps learning from the manager and the staff.”Parkin added: “It’s terrific. I’ve been in this position before when I was at Rochdale and had Grant Holt (now at Wigan) and Ricky Lambert (Southampton). It makes you sleep a bit better at night knowing that you’ve got a goal threat. That’s what he is.“Nahki’s blessed with pace and he’s got two good feet. He is also getting better at other things which he needs to do. The main thing is he keeps listening and learning from the manager and others.”Argus writer Simon Parker said “Gone is the one-dimensional goal chaser who was all pace and shooting. He’s is becoming a more rounded team player with a growing football intelligence.”But Parkin warned: “For me, he’s still got a long way to go. But he’s got a good attitude and the other players don’t let him get too big for his boots.“He’s got to remember what’s got him there — the time and effort that other people have put in and his team-mates. It’s not all about him and Nahki realises that.”
