Welcome to Saturday’s round-up of all the biggest and boldest Premier League transfer rumours that have been in the media over the past 24 hours – and we’ll start in North London, with a report which has Ange Postecoglou preparing to hit the January sales.Tottenham Hotspur spent much of the summer transfer window trying to find a new midfielder without success (the up-and-coming Lucas Bergvall aside) but may have found a solution – according to TeamTalk, Spurs are preparing to make a January move for Valencia midfielder Javi Guerra.The highly-rated 21-year-old is valued at £29m by his club, although Spurs will apparently try to negotiate a “more reasonable” price tag if they can. Guerra had been linked with Manchester United as well, but they’re out of the picture after signing Manuel Ugarte.The 3AM Verdict: A hard-working defensive midfielder with good tackling skills, Guerra is still raw and has a lot of development still to do but he’s been impressive with a poor Valencia side and a big move seems inevitable. £29m doesn’t sound too ‘unreasonable’ in the current market, either. One note of caution – one of the article’s sources is Spanish outlet Fichajes, who are notoriously unreliable.
