Tottenham Hotspur supporters are calling for the club's board to deliver a "credible explanation" of their approach in the summer transfer window, following the failure to complete a deadline day deal for West Bromwich Albion striker Saido Berahino. Four bids, two of which came in the final hours of the window, were rejected for the 22 year old, leaving the club with wafer-thin attacking options heading into the new season.

Last season's top scorer Harry Kane, who is yet to find the net this term, is the only senior striker available to Spurs boss Mauricio Pochettino. Despite the signings of Clinton N'Jie and Son Heung-min the club look lightweight in the attacking third. Emmanuel Adebayor remains frozen out at the club after failing to agree a move away on deadline day, while Roberto Soldado has joined Villarreal.

West Brom chairman Jeremy Peace has revealed that during the negotiations regarding Berahino, Tottenham continued to submit offers below the striker's asking price while the timing of the final two bids have also been criticised. The club's refusal to meet Berahino's price tag earlier in the window comes amid the revealing of accounts for the year to 30 June 2014, where they made pre-tax profits of £80m ($122.2m).

"At the end of this season's transfer window we find ourselves questioning where we have ended up," the statement from the Tottenham Hotspur Supporters Trust read. "Some areas of the squad have looked light as we played four games in August, and that remains the case as we move into the main part of the season. We welcome the good signings that have been made, but are concerned at the gaps that still exist and the pressure this places on the manager and the team.

"Spurs made the highest ever pre-tax profit in the Premier League last year – £80m. Revenues went up 22% to £180.5m. Ticket prices for top class games remain among the highest in the Premier League. Next year, the club has informed us it wants to increase those prices."

The 2016-17 campaign will be Tottenham's final year at White Hart Lane, before moving into their new 61,000 stadium for the start of the 2018-19 term – spending a season in-between ground-sharing at a to-be-confirmed stadium. Chairman Daniel Levy has pledged to continue to invest in the transfer market despite having to finance a new stadium, but supporters are not convinced.

"Many supporters are now questioning the relationship between what we pay and what we receive," the statement added. "We understand the club is trying to finance a new stadium, but we have also heard that this will not be allowed to unduly affect the playing side. And no doubt we will be asked to dig deep to watch the team in the new stadium, once it is built.

"This is not the first time the team has gone into a season looking light. We believe fans have shown enormous patience over the years. But we understand why that patience is starting to run out. It is important the club is run on successful business lines, but the success of the business depends on sporting success – the kind that attracts crowds and fills new stadiums."
