Chelsea take on Pep Guardiola\'s side with an impressive home record. Adam Bate thinks Lionel Messi will have the last word at Stamford Bridge though.Chelsea find themselves in the unusual position of being underdogs on their own patch when they host Barcelona at Stamford Bridge on Wednesday evening.Roberto Di Matteo’s side have had little over 72 hours to recover from their exertions in beating Tottenham in the FA Cup semi-final at Wembley on Sunday but the Chelsea boss is sure to make changes for this one.There have been some memorable Champions League nights between the two sides over the years. Indeed, John Terry and Frank Lampard will have fond memories of scoring in a 4-2 win against Barcelona to eliminate them from the competition back in 2005.Chelsea are 7/2 (4.5) to win this one and a first-leg draw can be backed at 11/4 (3.75).But Paddy Power make Barcelona the odds-on favourites to win at Stamford Bridge and surely end any hopes the London side have of reaching the final.Pep Guardiola’s side have had the occasional slip-up on their travels this season and failed to beat Milan away from home in the previous round but their recent La Liga form has been imperious.Barca have won their last 11 league games and are 8/13 (1.73) to win here.Lionel Messi – with 63 goals for the season – is an obvious favourite in the goalscoring markets and is available at 5/2 (3.5) with Paddy Power to be the last goalscorer in this one.That’s a good price given that Messi has completed the scoring in 12 of Barcelona’s 33 league games this season.For Chelsea, Frank Lampard is a good price at 11/1 (12.0) to open the scoring – remarkably long odds given his record of a goal every third game for the Blues.That’s the Value Bet in this one given that Barcelona have conceded first in their last two away games. But for the Bet of the Day, it is impossible to look beyond Messi.
