Premier League champions Manchester United have returned with a fresh bid for Spain international Cesc Fabregas. The London Evening Standard believes Old Trafford chiefs have made a £30m bid for the 26-year-old, as new boss David Moyes waits for the first high-profile signing of his new post.

Unfortunately for the Scot and United fans, the wait may be a little longer than they would like. Sky Sports believes Barcelona will not take a decision on the midfielder's future as yet. The Spanish champions are still reeling from the shock departure of manager Tito Vilanova, who announced his resignation over the weekend.

Club president Sandro Rosell, speaking after Vilanova's announcement, confirmed a new appointment by the end of the week. And it will fall to this new manager to decide on Fabregas' future, much as new Real Madrid boss Carlo Ancelotti has had to deal with Gonzalo Higuain's future.

Although nothing has been confirmed as yet, early reports suggest the short-list to replace Vilanova is short. There are only two names that have cropped up repeatedly.

The first is another former Barcelona player - Luis Enrique.

The appointment of the 43-year-old ex-Spanish international forward will continue the Catalans' recent tradition of finding leaders from within their playing history and philosophy, with both Pep Guardiola and Vilanova having played for the club; although, in the latter's case, it was only for the Barcelona B team.

However, Enrique is presently contracted to top division side Celta Vigo and only assumed charge of first team affairs at the Balaídos in early June. He signed from Serie A club AS Roma.

According to Spanish newspaper Marca, Enrique has begun pre-season work with the Galician club, who open their 2013/14 La Liga campaign at Real Valladollid on 17 August. The report also adds the former Barcelona player has remained non-committal regarding his future.

Argentine coach Marcelo Bielsa is another possibility, with an AS poll indicating Barcelona fans want him to succeed Vilanova. The 58-year-old manager has considerable experience, at both club and international levels, having coached both Argentina and Chile. He also coached Spanish club Athletic Bilbao for two seasons, until his contract expired in June.

Bielsa received particular praise from Guardiola last season. The present Bayern Munich boss called the South American the "best coach in the world". The Champions League-winning boss told Canal Athletic, "We must congratulate Athletic. We face the best coach in the world. Athletic footballers [play] a very honest game."

Meanwhile, AS believes another Argentine is in the frame as well - Gerardo Martino. The 50-year-old is believed to be in advanced talks already, with Barcelona sporting director Andoni Zubizaretta believed to be a big fan. Martino is presently unemployed, having left hometown club Newell's Old Boys recently.

A couple of Premier League names are also in the hat, with Tottenham's Andre Villas-Boas and Swansea City's Michael Laudrup finding mention in polls conducted by AS and Marca.
