Barcelona are readying one final offer for Chelsea defender David Luiz, the Mirror understands.

The Catalan club are desperately trying to strengthen their back line ahead of their title defence, and have identified the Brazilian international as their top transfer target.

However, they are set to be disappointed, as the Blues have insisted that they are not willing to part company with the 24 year old, who has made over 100 appearances for the club since signing from Benfica back in January 2011.

Meanwhile, Frank Lampard has declared himself fit for next weekend’s Premier League game against Hull City at Stamford Bridge.

The 35 year old, who may also feature in England’s friendly international against Scotland at Wembley on Wednesday, has missed the majority of Chelsea’s preseason with an Achilles injury.

However, he returned for the clubs 3-1 defeat to Real Madrid last Wednesday, before scoring a trademark long-range effort in the 2-1 win over Roma in the early hours of Sunday morning.

Romelu Lukaku did his chances of securing a starting berth for the season opener, after hitting a late winner – sparing new signing Mark Schwarzer’s blushes after the veteran keeper gifted the Italian’s an opener on twenty minutes.
