Arsenal boss Arsene Wenger claims that "some teams are on holiday" as the Premier League season draws to its conclusion.
Arsenal face the already relegated Sunderland on Tuesday; the Gunners now sit three points adrift of fourth placed Manchester City.
Sanchez has been linked with a move to Manchester City, among other clubs, and his manager believes one of the hottest properties in Europe is a more complete player than when he moved to Emirates Stadium from Barcelona in 2014.
They need the Reds to fail to beat relegated Middlesbrough at Anfield on Sunday to realistically stand any chance of maintaining Wenger's record of never finishing outside of the top four in a full season at the helm.
"I don't want to judge that", he said when asked whether West Ham had failed to put in a performance on Sunday to match their surprise victory over title-chasing Tottenham last week. It wasn't easy on Saturday, but we wanted to win and get a result for the supporters.
"In the last two seasons the team that won the league hasn't played in Europe".
Manchester United are also set to finish outside the top four, although they could still make the Champions League if they win the Europa League final against Ajax.

Pirates catcher Chris Stewart took a retaliatory pitch from Tom Wilhelmson in the ninth inning, and now bygones are bygones. The D-Backs would go on to score 11 runs in the third and fourth innings combined. "It got away from me", he said.
"If you are in any doubt, look at our season and compare that to Chelsea, Juventus and Atletico Madrid".
"We basically had two leagues, the top six and the rest".
Arsenal won this game at a stroll apart from a frantic few minutes in the second half and are desperately trying to claw their way into the top four.
Young defender Rob Holding, impressive in a back three, says the dressing room is totally focussed on one of Arsenal's customary strong finishes.
"We let ourselves down really".
"We knew that at the start of the game, so we knew we had to win no matter what. But, look, I don't know what will happen next season", he said. With two league games left and an FA Cup final now's surely the time to all get behind the team.
The Chilean global was instrumental in Arsenal's 4-1 win away at Stoke City on Saturday, but had to be replaced after receiving a kick to his thigh.
