Napoli's highly-rated Slovakian midfielder, Marek Hamsik, has issued a warning to his team mates that Chelsea will not be an easy team to beat, when the two sides square-off for the second leg of their Champions League tie on Wednesday night.

The two met in Naples for the first leg on 21 February, when a young and energetic Napoli dismantled the Blues 3-1. That defeat was, perhaps, the beginning of the end for former boss Andre Villas-Boas, who was fired less than a fortnight after, in the wake of a 0-1 defeat to West Brom.

However, interim boss Roberto Di Matteo seems to have found some spark within the club and has overseen two wins in his first two games in charge at Stamford Bridge - a 2-0 win over Birmingham in a replay of a FA Cup tie and a 1-0 league win at home to Stoke City.

"Villas-Boas' sack does not favour us, Chelsea showed a new spirit in the last two matches. However, we are only thinking about ourselves. This will be an important match and we trust our capacities. They will surge forward in attack to level the tie, we can hit them on the counter," Hamsik, the 24-year-old captain of the national team explained, in an article by

Chelsea will have to win 2-0 on the night to progress to the quarter-finals of the Champions League. They do have an away goal to their name, courtesy of Juan Mata's 27th minute strike at the Stadio San Paolo but the Blues will be aware they cannot afford to concede on Wednesday.
