Whilst Arsenal failed to sign an outfield player, and David De Gea's move to Real Madrid fell through in dramatic fashion, it was a tweet by West Brom striker Saido Berahino that sparked arguably the biggest story of deadline day.

The young striker has been linked with a move away from the Hawthorns all summer, with Spurs acknowledged as the club who would make a move.

Before yesterday's deadline day, Spurs had made two bids for Berahino that were rejected out of hand by Baggies chairman Jeremy Peace, who made a public statement about both transfers when they were made.

Spurs made two more bids yesterday to try and force Peace's hand but he again rejected the bids, reaffirming his stance that Berahino would not be sold unless the money offered was acceptable in his eyes.

But as the window closed at 6pm, Berahino took to Twitter to show his frustration that the move was not allowed to happen, saying "Sad how i cant say exactly how the club has treated me but i can officially say i will never play Jeremy Peace"

The tweet makes it clear that the striker's problem is with the club's chairman, as opposed to manager Ton Pulis, who has invested a lot of time in trying to keep the player happy in recent months.

When Pulis took over last season, Berahino was being ridiculed by his own teammates for his lack of effort on the pitch, but the former Stoke boss has since done a lot to smooth things over and build a squad that are on the same page.

It is understood that Pulis was in fact hoping that Berahino's move would go through, having not played Berahino for the last three games as he feels he has been 'affected' by the speculation, something which yesterday's tweet clearly suggests.

But it remains to be seen whether Pulis can mend the bridges again now that the player has essentially said he is going on strike, both in the dressing room and with the chairman.

Logistically, if Berahino does refuse to play, the club have several options, ranging from suspension and fines to terminating his contract at the club.

The chances of Jeremy Peace terminating his contract and allowing him to leave, which was what he wanted to avoid in the first place, are slim to say the least, and especially for nothing.

Peace has yet to comment on what Berahino has said, but we won't know how this situation will be resolved until after the international break, when players return to their clubs.
