Joe Cole insists Chelsea should be frustrated with their Champions League semi-final first-leg result at Real Madrid as they should have put the tie to bed.
Thomas Tuchel's Blues drew 1-1 away at the 13-time European champions on Tuesday night and while they took a vital away goal back to west London for next week's return leg, the visitors missed a great deal of chances to add to their tally.
Despite their slender advantage going into the Stamford Bridge tie next Wednesday, former Blues winger Cole believes Tuchel should have used his substitutions better to try and get a result.
